The method utilizes a combination of key set checks and string matching to find and return the relevant options.


The provided Java code defines a method `validateSubType` that checks if a given class type is allowed for deserialization based on certain security criteria. It verifies if the class name is in a list of illegal class names and checks if the class is not an interface and starts with a specific prefix. If the class fails these checks, a `JsonMappingException` is thrown to prevent deserialization for security reasons.


The provided Java code defines a method `getLine(int lineNumber)` that retrieves a specific line of text from a string containing code, which is obtained from the `getCode()` method. It handles line retrieval by tracking the current position and line number, and it uses newline characters to determine line boundaries. If the requested line number exceeds the available lines, or if an error occurs while fetching the code, it returns `null`.


The provided Java code defines a private method `_mapType` that takes a `Class<?>` parameter `rawClass` and returns a `JavaType` representing the type of a map. If `rawClass` is `Properties`, it constructs a `MapType` with both key and value types as `String`. Otherwise, it attempts to find the type parameters for `rawClass` as a `Map`, and if successful, constructs a `MapType` with the identified key and value types; if not, it returns a `MapType` with unknown types or throws an exception if the type parameters are not as expected.


The provided Java code defines a method `cumulativeProbability` that calculates the cumulative probability of a normal distribution for a given value `x`, using the error function (Erf) to compute the result based on the mean and standard deviation. If the calculation exceeds the maximum number of iterations, it returns 0.0 for values significantly below the mean and 1.0 for values significantly above the mean, while rethrowing the exception for values within that range. The method is designed to handle potential numerical issues in the computation.


The provided Java code defines a method `collect` that analyzes a JavaScript AST (Abstract Syntax Tree) node to determine if it represents a variable or property assignment (set) or access (get). It identifies the type of the node (e.g., getter, setter, variable, property) and checks if the name is a global reference within the given scope. Depending on whether the node is a set or get operation, it calls appropriate handling methods for global or local scope.


The provided Java code defines a method `flipIfWarranted` that checks if a certain condition involving an array `work` is met; specifically, it compares 1.5 times an element at index `pingPong` with another element in the array. If the condition is satisfied, it reverses a segment of the `work` array, specifically the elements from index `0` to `4 * (n - 1)`, in groups of four. The method returns `true` if the array was flipped and `false` otherwise.


The provided Java code defines a method `evaluate` that calculates the variance of a weighted dataset, given an array of values, their corresponding weights, a mean, a starting index, and a length. It first checks if the input data is valid using the `test` method, then computes the weighted variance, either biased or unbiased based on the `isBiasCorrected` flag. The method returns the calculated variance, or `NaN` if the input data is invalid or if the length is less than 1.


The provided Java code defines a method called `prelim`, which is part of an optimization algorithm that manages interpolation points and evaluates a mathematical model within a trust region framework. It initializes various matrices and parameters, iteratively updates interpolation points based on objective function evaluations, and adjusts the model's second derivatives and gradients to refine the search for an optimal solution. The method handles boundary conditions and exceptions related to the exploration of the optimization path.


The provided Java code defines a generic method `addAll` that combines two arrays of the same type into a new array. If either input array is null, it returns a clone of the other array.

The provided Java code defines a method `tryMinimizeIf` that attempts to optimize an `if` statement represented by a `Node` in an abstract syntax tree (AST). It evaluates various conditions and transformations, such as simplifying the `if` statement when both branches are foldable expressions, handling variable assignments, and restructuring the code to minimize redundancy or improve efficiency. The method modifies the AST in place and reports any changes made during the optimization process.


The provided Java code defines a constructor for a class named `Base64`. This constructor calls another constructor in the same class, passing the integer value `0` as an argument. This suggests that there is an overloaded constructor that takes an integer parameter, which is likely used to initialize the object in a specific way.


The provided Java code defines a method `visitNew` that processes a node representing a constructor call in a type-checking context. It retrieves the constructor's type and checks if it is a valid constructor type; if so, it visits the parameter list and ensures the node is typed with the constructor's instance type. If the type is not a valid constructor, it reports an error and ensures the node is typed without specific instance type information.


The provided Java code defines a method `deserialize` that takes a `JsonParser` and a `DeserializationContext` as parameters and returns an `ObjectNode`. It checks if the parser is at the start of an object or a field name to proceed with deserializing an object; if it encounters an end object token, it returns an empty `ObjectNode`. If neither condition is met, it throws a mapping exception indicating that an `ObjectNode` is expected.


The provided Java code defines a method `_add` that adds an `Annotation` object to a map called `_annotations`, which maps annotation types to their corresponding annotation instances. If the map is null, it initializes it as a new `HashMap`. The method returns `true` if the annotation was added successfully or if it differs from a previously stored annotation of the same type; otherwise, it returns `false`.


The provided Java code defines a method `multiply` that takes an integer `x` as an argument. If `x` is within the range of 0 to `RADIX - 1`, it calls a fast multiplication method `multiplyFast(x)`. Otherwise, it creates a new instance of the class with `x` and calls a more general `multiply` method.

It sets various properties for the pie chart, including removing the legend, setting a background color, and adding a title with specific formatting. Additionally, it initializes fields for aggregated items and their appearance.


The provided Java code defines a static method `createNumber` that takes a string representation of a number and attempts to convert it into a `Number` object (such as `Integer`, `Long`, `Float`, `Double`, or `BigDecimal`). It handles various formats, including hexadecimal, scientific notation, and suffixes for different numeric types, while also validating the input string and throwing `NumberFormatException` for invalid cases. The method also checks for special conditions, such as blank strings and specific character suffixes, to determine the appropriate numeric type to return.


The provided Java code defines a method `declareNameInScope` that updates a `FlowScope` based on the type of a given `Node`. It handles three cases: if the node is a name, it infers its type; if it's a property access (GETPROP), it infers the type of the qualified name; and if it's a `THIS` reference, it does nothing. If the node type does not match any of these cases, it throws an `IllegalArgumentException`.


The provided Java code defines a private method `inferPropertyTypesToMatchConstraint` that takes two parameters: `type` and `constraint`, both of type `JSType`. If either parameter is null, the method returns early; otherwise, it attempts to cast the `constraint` to an `ObjectType` after restricting it to non-null and non-undefined values. If the cast is successful, it calls the `matchConstraint` method on the `type` with the constrained object type.


The provided Java code defines a static method `parseInputStream` that reads an `InputStream`, detects or sets the character encoding, and parses the content into a `Document` object using a specified `Parser`. It handles BOM (Byte Order Mark) detection, checks for charset declarations in the document's metadata, and falls back to a default charset if necessary. Finally, it ensures the document's output settings reflect the determined charset before closing the input stream and returning the parsed document.


The provided Java code defines a method `density` that calculates the density of a multivariate normal distribution given an array of values. It first checks if the length of the input array matches the expected dimension; if not, it throws a `DimensionMismatchException`. If the dimensions are correct, it computes and returns the density using a formula that incorporates the determinant of the covariance matrix and an exponent term derived from the input values.


The provided Java code defines a constructor for a class named `BasePeriod`, which takes a `long` duration as an argument. It initializes the period type to time, retrieves an array of integer values representing the duration in a specific format using the ISO chronology, then changes the period type to standard and copies the relevant values into an internal array `iValues`. The constructor effectively sets up the period representation based on the given duration.


The provided Java code defines a method `isSubtype` that checks if the current `ArrowType` instance is a subtype of another `JSType` instance. It first verifies that the other type is also an `ArrowType`, then compares their return types and parameters, considering optional and variable arguments. The method returns `true` if the current type is a valid subtype based on these criteria, and `false` otherwise.


The provided Java code defines a method `process` that handles various types of HTML tokens (such as characters, comments, start tags, end tags, and EOF) within an HTML tree builder context. It processes these tokens according to HTML parsing rules, managing the document structure by inserting elements, handling formatting, and ensuring proper nesting and scope of elements. The method includes error handling for invalid structures and transitions between different parsing states as needed.


The provided Java code initializes compiler options by setting up an error manager based on the presence of an output stream and configuring various diagnostic checks based on the specified options. It manages warning levels for type checking and global variable checks, and composes a list of warnings guards to control the reporting of warnings during compilation. Additionally, it ensures that certain checks are disabled if specific conditions are met.


The provided Java code defines a protected method called `getInitialDomain` that takes a double parameter `p`. It initializes a variable `ret` to 1.0 and retrieves the value of degrees of freedom using the method `getDenominatorDegreesOfFreedom()`. If the degrees of freedom `d` is greater than 2.0, it updates `ret` to the value of `d / (d - 2.0)` before returning it.


The provided Java code defines a method `append` in the `EqualsBuilder` class that compares two objects (`lhs` and `rhs`) for equality. It first checks if the comparison should proceed based on the current equality state and whether the objects are the same or one of them is null. If the objects are arrays, it recursively compares their elements based on their specific types; otherwise, it uses the `equals` method or `compareTo` for `BigDecimal` to determine equality.


The provided Java code defines a private method `_verifySharing()` that checks if a shared hash structure has been modified. If it has, it creates copies of the `_hashArea` and `_names` arrays, sets the `_hashShared` flag to false, and calls `_verifyNeedForRehash()`. Additionally, if a rehash is needed, it invokes the `rehash()` method.


The provided Java code defines a method `compareTo` that compares two `Fraction` objects based on their values. It calculates the cross-products of the numerators and denominators to avoid floating-point inaccuracies, returning -1 if the current fraction is less than the other, +1 if it is greater, and 0 if they are equal. This method allows for natural ordering of `Fraction` objects.


The provided Java code defines a method `getOffsetFromLocal` that calculates the time zone offset for a given local time instant.

If there are discrepancies, it evaluates transitions to determine the correct offset, ultimately returning the appropriate offset based on the conditions checked.


The provided Java code defines a method `getDeclaredType` that determines the type of a variable based on its associated JSDoc information and the value assigned to it. It checks for various conditions, such as the presence of type annotations, whether the right-hand value is a function or an object literal, and handles special cases for constants and enums. If no suitable type can be determined, it defaults to retrieving the declared type from the annotation.


The provided Java code defines a method `tryFoldArrayJoin` that optimizes an array join operation by folding the elements of an array into a single string when possible. It checks if the input node represents a call to the `join` method on an array, processes the array elements to concatenate their string values with a specified delimiter, and replaces the original node with the resulting string or modified array as needed. The method also includes checks to ensure that the optimization is beneficial in terms of code size and structure.


The provided Java code defines a method `solve` that attempts to find a root of a univariate real function `f` within a specified interval `[min, max]`, using an initial guess `initial`. It evaluates the function at various points to check for roots and handles cases where the function values at the endpoints or the initial guess are close to zero, indicating a root. If the function values at the endpoints do not bracket a root, it throws an exception indicating that the input does not satisfy the necessary conditions for root-finding.


The provided Java code defines a method `findNameForSerialization` that retrieves the name for serialization from an `Annotated` object. It first checks for the presence of a `JsonGetter` annotation to get the name; if not found, it checks for a `JsonProperty` annotation. If neither is present but other specific annotations are found, it returns an empty name; otherwise, it returns null.


The provided Java code defines a method called `revert()` within a class (presumably `Line`) that creates a new instance of `Line` by copying the current instance. It then negates the `direction` property of the new instance before returning it. This effectively creates a reversed version of the original line.


The provided Java code defines a method `createBoundField` that creates a `BoundField` for serialization and deserialization using Gson. It checks for a `JsonAdapter` annotation on a field to determine if a custom type adapter should be used; otherwise, it retrieves the default type adapter for the field's type. The `BoundField` includes methods for writing the field's value to JSON and reading it back, handling cases for primitive types and null values appropriately.


The provided Java code defines a method `meet` that computes the intersection of two `JSType` objects, `this` and `that`. It uses a `UnionTypeBuilder` to collect types that are subtypes of either `this` or `that`, and builds a resulting type. If the resulting type is not valid, it returns a "no type" or "no object type" based on the nature of the input types.


The provided Java code defines a method `_addExplicitAnyCreator` that processes a `CreatorCandidate` to determine how to add a creator to a `CreatorCollector` based on the parameters of the candidate. It checks if the candidate has a single parameter and whether it has an explicit name or injection value, and then constructs a property creator if applicable. If the conditions for using properties are not met, it handles the single argument creator differently and may remove constructor definitions from the associated property definition.


The provided Java code defines a method `checkInterfaceConflictProperties` that checks for conflicts between properties of an interface and its extended interfaces. It compares the property types of the current interface with those in a given set of properties, reporting any incompatibilities found.

The method uses a `StringBuffer` to build the final string efficiently.


The provided Java code defines a method `_deserializeFromEmptyString()` that returns specific default values based on the value of the `_kind` variable. If `_kind` is `STD_URI`, it returns an empty URI; if it is `STD_LOCALE`, it returns the root locale. For any other value of `_kind`, it calls the superclass's implementation of the method.


The provided Java code defines a method `absUrl` that takes an attribute key as input and returns the absolute URL corresponding to the relative URL associated with that key. It first checks if the attribute key is not empty and if the attribute exists; if not, it returns an empty string. If the base URI is valid, it constructs the absolute URL from the base URI and the relative URL, handling cases where the relative URL starts with a query string or is malformed.


The provided Java code defines a method `parse` that takes a string representation of a complex number and a `ParsePosition` object to parse the real and imaginary parts of the number. It first extracts the real part, then checks for a sign indicator for the imaginary part, and finally verifies the presence of the imaginary unit. If any parsing step fails, it resets the position and returns null; otherwise, it returns a new `Complex` object with the parsed values.


The provided Java code defines a method `_typeFromId` that takes a string `id` and a `DatabindContext` object `ctxt` to construct a `JavaType` based on the given `id`. If the `id` contains a generic type indicator ('<'), it constructs a type from the canonical representation and checks if it is a subtype of a specified base type; otherwise, it attempts to find the class corresponding to the `id`. If the class is found, it constructs a specialized type; if not, it handles the error appropriately based on the context.


The provided Java code implements a Rectangular Cholesky Decomposition algorithm for a given real matrix, which decomposes the matrix into a product of a lower triangular matrix and its transpose.

The resulting lower triangular matrix is stored in a new matrix called `root`.


The provided Java code implements a function called `caverphone` that transforms an input string according to specific phonetic rules, primarily aimed at generating a Caverphone representation of the text. It processes the input by converting it to lowercase, removing non-alphabetic characters, and applying a series of regex-based replacements to modify the string based on phonetic patterns. Finally, it appends a fixed string to ensure the output is 10 characters long, returning the first 10 characters of the modified string.


The provided Java code defines a method `read` that reads bytes from an input stream into a specified byte array (`dest`) starting at a given offset (`offs`) for a specified length (`len`). It performs various checks to ensure the parameters are valid, such as ensuring offsets and lengths are non-negative and do not exceed the bounds of the destination array. The method reads bytes until either the specified length is reached or the end of the stream is encountered, returning the number of bytes read or -1 if no bytes were read.


The provided Java code defines a method `reciprocal()` for a `Complex` class that calculates the reciprocal of a complex number. It handles special cases such as NaN (not a number), zero, and infinity, returning appropriate values for each case. For valid complex numbers, it uses a conditional approach to compute the reciprocal based on the relative magnitudes of the real and imaginary parts.


The provided Java code defines a method `read()` that overrides a superclass method to read a character from an input stream. It increments a `lineCounter` each time it encounters a newline character (`'\n'`) that is not preceded by a carriage return (`'\r'`), while also keeping track of the last character read. The method returns the last character read from the stream.


The provided Java code is an implementation of a visitor pattern that analyzes nodes in an abstract syntax tree (AST) during a traversal. It checks for non-empty return statements, records variable assignments, and identifies escaped variables and qualified names based on their scope. The logic ensures that only local variables and names are processed, and it collects data related to their usage and scope.


The provided Java code defines a method `toStringHelper` that generates a string representation of an object type, either by returning its reference name or by pretty-printing its properties if the `prettyPrint` flag is set to true. It collects the names of the object's own properties and their types, limiting the output to a maximum number of properties defined by `MAX_PRETTY_PRINTED_PROPERTIES`. If the `forAnnotations` flag is true, it returns a placeholder string; otherwise, it returns a simplified representation when not in pretty-print mode.


The provided Java code defines a method `buildWriter` that constructs a `BeanPropertyWriter` for serializing a property of a Java bean.

If the JSON structure is not as expected, it throws exceptions to indicate the errors.


The provided Java code defines a method `apply` that checks if a given `Node` object has side effects or represents a deletion operation. It returns `true` if the node is a function call or constructor call with side effects, or if it is a property deletion node.

The provided Java code defines a static method `modify` that adjusts a `Calendar` object based on a specified field (such as seconds, minutes, or semi-month) and a rounding flag. It first checks for large calendar values and handles milliseconds, seconds, and minutes by potentially subtracting their values from the current time. The method then rounds the specified field according to certain conditions and updates the `Calendar` object accordingly, throwing an exception if the field is unsupported.


The provided Java code defines a method `getPct` that takes an `Object` as a parameter and returns a `double`. It casts the input object to a `Comparable<?>` type and calls another overloaded `getPct` method that presumably processes the comparable value. This suggests that the method is designed to handle percentage calculations based on comparable objects.


The provided Java code defines a method `isPrototypePropertyAssign` that checks if a given assignment node (`assign`) is assigning a value to a property of an object's prototype. It verifies that the assignment is a simple left-hand side expression, specifically a chained property access (`GETPROP`), and checks if the second property in the chain is the string "prototype". If these conditions are met, the method returns true; otherwise, it returns false.


The provided Java code defines a method `insert` that processes a `Token.StartTag`. If the start tag is self-closing, it creates an empty element, adds it to a stack, transitions the tokeniser state to `Data`, and emits an end tag for the element. If the start tag is not self-closing, it creates a new element with the specified tag name and attributes, inserts it, and returns the element.


The provided Java code defines a method `_fromVariable` that takes a `TypeVariable` and `TypeBindings` as parameters. It retrieves the name of the type variable and checks if the context is null; if so, it initializes a new `TypeBindings` object.

The Java code defines a private static method `isReduceableFunctionExpression` that checks if a given `Node` object `n` is a function expression and not a key in a getter or setter. It utilizes utility methods from `NodeUtil` to perform these checks. The method returns a boolean value indicating whether the conditions are met.


The provided Java code defines a method `checkRequiredOptions()` that checks for any missing required options.

For qualified names, it checks if they exist in the provided set of defined names.


The provided Java code defines a method `getOffsetFromLocal` that calculates the time zone offset for a given local time instant.

If there are discrepancies, it evaluates transitions to determine the correct offset, ultimately returning the appropriate offset based on the conditions checked.


The provided Java code defines a method `answer` that handles mock object behavior based on the invoked method. If the method is a `toString` method, it returns a string representation of the mock object, including its type and hash code if it has a default name. If the method is a `compareTo` method, it compares the mock object with the first argument and returns 0 if they are the same, otherwise 1; for other methods, it returns a default value based on the return type.


The provided Java code defines a generic method `resetMock` that takes a mock object as a parameter. It retrieves the existing mock handler for the given mock, creates a new method interceptor filter based on the mock's settings, and then sets this new filter as the callback for the mock. This effectively resets the mock's behavior to its initial state.


The provided Java code defines a method `read` that reads bytes into a specified array `b` starting from a given `offset` and for a specified `len`. It performs various checks for null values and index bounds before reading data from an input stream, either encoding or decoding it using a `base64` object, and populating the byte array with the results. The method returns the number of bytes read, or 0 if no bytes are read.


The provided Java code defines a method `guessAOmega()` that calculates the parameters `a` and `omega` based on a set of observations, which are presumably points in a 2D space. It computes various integrals and sums related to the observations to derive these parameters, handling special cases where certain conditions lead to potential mathematical errors, such as division by zero.

The method returns the GCD, multiplied by a power of two based on the number of times both inputs were divisible by two.


The provided Java code defines a static method `stripLeadingHyphens` that removes leading hyphens from a given string. If the string starts with two hyphens ("--"), it removes both; if it starts with one hyphen ("-"), it removes just that one. If the string is null or does not start with a hyphen, it returns the string unchanged.


The provided Java code defines a method `deserialize` that reads JSON data from a `JsonParser` and copies its structure into a `TokenBuffer`. It checks if the current token is a field name and, if so, writes the start of an object, then continues to copy the structure until it encounters the end of the object. If the end of the object is not reached as expected, it throws a mapping exception.


The provided Java code defines a static method `getCharsetFromContentType` that extracts and returns the character set from a given content type string.

The provided Java code defines a static method `getTypeAdapter` that retrieves a `TypeAdapter` based on the specified `JsonAdapter` annotation. It checks if the annotation's value is a `TypeAdapter` or a `TypeAdapterFactory`, constructs the appropriate adapter using a `ConstructorConstructor`, and ensures the adapter is null-safe before returning it. If the value is neither a `TypeAdapter` nor a `TypeAdapterFactory`, it throws an `IllegalArgumentException`.


The provided Java code defines a static method `parseByteData` that takes a `ByteBuffer`, a character set name, a base URI, and a parser as parameters to parse byte data into a `Document`. If the character set is not specified, it attempts to detect it from the document's meta tags; if a different charset is found, it re-decodes the byte data accordingly. Finally, it parses the document and sets the output settings to the specified or detected charset before returning the `Document`.


The provided Java code defines a method `_addMethodMixIns` that adds methods from a mixin class to a target class's method map. It first identifies all superclasses of the mixin class, then iterates through the declared methods of each mixin class, checking if they are includable.

It checks if the function can be called based on its type, reports errors if it cannot, and handles specific cases for constructors and ordinary functions, including verifying the `this` type and processing the function's parameter list. Finally, it ensures that the node is typed correctly based on the function's return type or defaults to a general typing if the function type is not a `FunctionType`.


The provided Java code defines a method `format` that takes a `Calendar` object and a `StringBuffer` as parameters. If a flag `mTimeZoneForced` is true, it clones the calendar, sets its time zone to `mTimeZone`, and then applies formatting rules to the calendar using the `applyRules` method, returning the modified `StringBuffer`.


The provided Java code defines a protected method `_serializeXmlNull` that serializes a null value into XML format using a `JsonGenerator`. It first determines the root name for the XML from the configuration or defaults to a predefined constant if none is found.

The provided Java code defines a private method `toStringEquals` that takes a `Matcher` object and an `Object` as parameters. It compares the string representation of the `Matcher` (obtained using `StringDescription.toString(m)`) with the string representation of the `Object`, returning `true` if they are equal and handling `null` values appropriately. If the `Object` is `null`, it compares the `Matcher`'s string representation to the string "null".


The provided Java code implements a root-finding algorithm using the Regula Falsi method, which iteratively refines estimates of the root of a function based on two initial bounds, `x0` and `x1`. It evaluates the function at these bounds and updates them based on the computed values, applying different strategies (Illinois, Pegasus, or standard Regula Falsi) to adjust the function values. The loop continues until the function value is sufficiently close to zero or the change in estimates is within specified accuracy tolerances, returning the appropriate root based on the allowed side conditions.


The provided Java code defines a generic method `putIn` that takes a map of type `M` (which extends `Map<String, String>`) as a parameter. It iterates over a predefined `mapping` of string keys to integer values, using the integer values as indices to retrieve corresponding elements from a `values` array.

The method returns this collection of legend items.


The provided Java code defines a method `traverse` that recursively visits nodes in a tree-like structure. It first checks if the node should be visited; if so, it iterates through the node's children, recursively calling `traverse` on each child.

It performs calculations using temporary arrays to compute the magnitudes and angles, handling cases based on the sign of the x-coordinate to determine the correct quadrant for the angle. Finally, it stores the results in a specified result array, while also redundantly calculating the atan2 using the standard library method.


The provided Java code defines a method `createKeyDeserializer` that creates a `KeyDeserializer` for a given `JavaType` within a specified `DeserializationContext`. It first checks for custom key deserializers in the factory configuration, and if none are found, it defaults to creating an enum key deserializer or a standard string-based key deserializer based on the type. Additionally, if there are any deserializer modifiers in the factory configuration, it applies them to the created key deserializer before returning it.


The provided Java code defines a method `getLength()` that returns an integer value. It retrieves a base value using the `getBaseValue()` method; if the base value is `null`, it returns 1, otherwise, it returns the length of the base value using the `ValueUtils.getLength()` method.


The provided Java code defines a static method `createNumber` that takes a string input and attempts to parse it into a numeric type (such as Integer, Long, Float, Double, or BigDecimal). It handles various cases, including hexadecimal numbers, scientific notation, and suffixes for different numeric types, while also validating the input string and throwing `NumberFormatException` for invalid formats. The method returns the corresponding numeric object or null for specific cases, such as when the input is null or a blank string.


The provided Java code defines a method `solve` that attempts to find a root of a function `f` within a specified interval `[min, max]`. It first evaluates the function at the endpoints and checks if the function values have different signs, indicating the presence of a root. If the signs are the same and the values are close to zero, it returns the respective endpoint; otherwise, it throws an exception. If the signs are different, it calls another method to continue the root-finding process.


The provided Java code defines a method `validate` that checks a `WriteableCommandLine` object against a set of defined options. It counts the number of present options, validates each option, and ensures that the number of options used falls within specified minimum and maximum limits. If any unexpected options are found or required options are missing, it throws an `OptionException` with appropriate error messages.


The provided Java code defines a method `buildWriter` that constructs a `BeanPropertyWriter` for a specified property of a Java bean, taking into account various serialization configurations such as type handling, inclusion criteria, and null suppression. It determines the appropriate serialization type and value to suppress based on the property's annotations and default inclusion settings. Finally, it creates and returns a `BeanPropertyWriter` instance, potentially applying a null serializer and unwrapping transformer if specified.


The provided Java code defines a method `maybeDeclareQualifiedName` that processes a JavaScript node to potentially declare a qualified name based on its type and context. It checks for various conditions, such as whether the node represents a prototype or if it has an inferred type, and updates the type registry accordingly. If the type is not explicitly declared, it may add a stub declaration or define a property on the owner type based on the node's characteristics and the presence of a right-hand side value.


The provided Java code defines a method `cacheString` that attempts to cache and return a substring created from a character array (`charBuf`). If the substring's length exceeds a predefined maximum (`maxStringCacheLen`), it creates a new `String` object. Otherwise, it computes a hash to find an index in a string cache array (`stringCache`), checks if a string already exists at that index, and either returns the cached string or updates the cache with a new string if necessary.


The provided Java code defines a static method `toLocale` that converts a string representation of a locale into a `Locale` object. It validates the input string format, which can be either a two-letter language code, or a combination of language, country, and variant codes separated by underscores. If the input string does not conform to the expected format, it throws an `IllegalArgumentException`.


The provided Java code initializes a pattern parsing mechanism by extracting format fields from a given pattern string using a regular expression matcher. It iterates through the matched fields, applying strategies to build a regex pattern while collecting these strategies in a list. If the pattern is invalid or cannot be fully parsed, it throws an `IllegalArgumentException`, and finally compiles the constructed regex pattern for later use.


The provided Java code defines a method `createOptions()` that configures and returns a `CompilerOptions` object based on various flags and settings. It sets coding conventions, compilation levels, warning levels, and formatting options, and handles message bundles for translations. Additionally, it manages specific passes for Closure and jQuery optimizations based on the compilation level and flags provided.


The provided Java code defines a method `serialize` that takes an `Object` value and serializes it into JSON format using a `JsonGenerator`. It checks the type of the value: if it's a `String`, it uses it directly; if it's a `Date`, it uses a default serialization method; if it's a `Class`, it retrieves the class name; otherwise, it calls the object's `toString()` method. Finally, it writes the resulting string as a field name in the JSON output.


The provided Java code defines a method `removeUnreferencedFunctionArgs` that removes unreferenced function arguments from a given function scope if certain conditions are met, such as the `removeGlobals` flag being true. It checks if the function is part of a getter or setter and determines whether it can modify call sites. If modification is not allowed, it iteratively removes the last argument from the argument list if it is not referenced; otherwise, it calls an optimizer to handle the removal.


The provided Java code defines a method `read` that reads bytes from a current tar entry into a specified byte array, starting at a given offset and for a specified number of bytes. It checks for end-of-file conditions and ensures that there is a valid current entry before attempting to read. If the read operation is successful, it updates the total bytes read and the entry offset; otherwise, it handles errors such as reaching the end of the stream or encountering a truncated archive.


The provided Java code defines a method `isEmptyType()` that returns a boolean value indicating whether the current type is considered "empty." It checks if the type is classified as "no type," "no object type," or "no resolved type," or if it is equivalent to a specific native function type called `LEAST_FUNCTION_TYPE` from a registry. If any of these conditions are met, the method returns `true`; otherwise, it returns `false`.


The provided Java code defines a method `createContextual` that customizes a `JsonSerializer` based on the `JsonFormat` annotations found on a property. It checks for formatting options such as shape, pattern, locale, and time zone, and adjusts the date formatting accordingly, either by creating a new `SimpleDateFormat` or modifying an existing one. If the configured `DateFormat` is not compatible, it raises an error.


The provided Java code defines a method `isAssignedOnceInLifetime()` that checks if a variable, represented by a `Reference` object, is assigned exactly once within its lifetime. It retrieves the assignment reference and traverses its associated basic blocks to ensure that the assignment occurs only within a function scope and not within any loops. If these conditions are met, the method returns true; otherwise, it returns false.


The provided Java code defines a method `escape` that takes a `Writer` and a `String` as parameters and writes the escaped version of the string to the writer. It processes each character in the string, converting characters to their corresponding HTML entities if they are non-ASCII or if they have a defined entity name, and handles characters outside the Basic Multilingual Plane (BMP) appropriately. The method uses numeric character references for characters that do not have a named entity or are outside the ASCII range.


The provided Java code defines a method `matchConstraint` that checks if an object has a reference name; if not, it processes a given `constraintObj` of type `ObjectType`. If the `constraintObj` is a record type, it iterates through its properties, inferring types for any undeclared properties and defining them accordingly. If a property is not present in the current object, it infers its type as the least supertype of the property's type or as `VOID_TYPE`.


The provided Java code defines a method `traverseNew` that processes a `Node` object and updates its `JSType` based on the type of its constructor. It first traverses the children of the node, retrieves the constructor's type, and checks if it is a valid constructor type. If so, it sets the node's type to the instance type of the constructor and performs backward inference from the call site.


The provided Java code defines a method `chiSquare` that calculates the chi-square statistic based on expected and observed frequency arrays. It first checks for valid input conditions, including the lengths and positivity of the expected values and non-negativity of the observed values. If the total observed and expected values differ significantly, it rescales the expected values before computing the chi-square statistic using the formula for deviations squared divided by expected values.


The provided Java code defines a method `indexOf` that searches for the first occurrence of a specified substring (`str`) within a larger character buffer, starting from a given index (`startIndex`). It handles various edge cases, such as null strings, empty substrings, and invalid start indices, and returns the index of the first match or -1 if no match is found. The method uses a nested loop to compare characters of the substring with the characters in the buffer.


The provided Java code defines a method `getCurrentStream()` that returns an `InputStream` for the current entry in a 7z archive. If the size of the current entry is zero, it returns an empty byte array stream. If there are multiple deferred block streams, it skips and closes all but the first one before returning that stream; if no entry is available, it throws an `IllegalStateException`.


The provided Java code defines a method `acceptStep` that processes events during a numerical integration step using an `AbstractStepInterpolator`. It evaluates and handles events based on their occurrence times, updating the state of the system and invoking step handlers accordingly. The method also manages the transition between event states and checks for termination conditions, returning the current time after processing all events.


The provided Java code defines a generic method `putIn` that takes a map of type `M` (which extends `Map<String, String>`) as an argument. It checks if a variable `mapping` is not null, and if so, iterates over its entries to retrieve integer values corresponding to string keys. For each entry, it puts the value from the `values` array into the map at the key specified by the entry, provided the index is within the bounds of the array.


The provided Java code defines a method `isShortOption` that checks if a given token represents a valid short option. It first verifies that the token starts with a hyphen and is longer than one character. Then, it extracts the option name (ignoring any assignment) and checks if it exists in a collection of short options using the `options.hasShortOption` method.


The provided Java code defines a method `canInlineReferenceDirectly` that determines whether a function call can be inlined directly based on certain conditions. It checks if the function node is suitable for inlining, verifies the arguments passed to the function, and ensures that there are no side effects or mutable state issues that would prevent inlining. If all conditions are met, it returns a result indicating that inlining is possible; otherwise, it returns a result indicating that it is not.


The provided Java code defines a method `findCalledFunctions` that recursively traverses a tree structure represented by `Node` objects. It checks if each node is of type `Token.NAME` and if it qualifies as a candidate usage, in which case it adds the node's string representation to a set called `changed`. The method ensures that the `changed` set is not null and processes all child nodes of the current node.


The provided Java code defines a method `parsePattern()` that processes a date/time pattern string (`mPattern`) and generates a list of `Rule` objects based on the tokens found in the pattern. It utilizes `DateFormatSymbols` to retrieve locale-specific representations for various date components (like eras, months, weekdays, etc.) and constructs rules for formatting or parsing these components based on the token type (e.g., year, month, day, etc.). The method handles different token lengths and types, throwing an exception for illegal pattern components.


The provided Java code defines a method `getNumUseInUseCfgNode` that counts the number of times a variable (identified by `varName`) is used within a given control flow graph node (`cfgNode`). It uses a callback class `AbstractCfgNodeTraversalCallback` to traverse the nodes, incrementing a counter (`numUsesWithinCfgNode`) whenever it encounters a name node that matches `varName`, unless the name is part of an assignment chain. The method also includes a helper function `isAssignChain` to determine if the current node is part of a chain of assignment nodes leading up to the specified ancestor node.


The provided Java code defines a method `processResponseHeaders` that processes HTTP response headers stored in a map. It iterates through each header entry, handling "Set-Cookie" headers by extracting and storing cookie names and values, while other headers are either stored as single values or concatenated if multiple values exist. The method utilizes a `TokenQueue` to parse cookie strings and calls `cookie` and `header` methods to store the processed data.


The Java method `parseContextTypeExpression` takes a `JsDocToken` as an argument and checks if it is a question mark (`JsDocToken.QMARK`). If it is, the method creates and returns a new node of type `Token.QMARK`. Otherwise, it calls another method, `parseBasicTypeExpression`, to handle the token and return the corresponding node.


The provided Java code defines a method `read` that reads a JSON date value using a `JsonReader`. If the JSON value is null, it returns null; otherwise, it deserializes the date string into a `Date` object. Depending on the specified `dateType`, it returns the date as either a `Date`, `Timestamp`, or `java.sql.Date`, throwing an error for unsupported types.


The provided Java code defines a method `annotateCalls` that processes a `Node` object, which is expected to represent a function call. It traverses the child nodes to find the first non-cast child and checks if it is a property access; if not, it marks the call as a "free call." Additionally, if the first child is a name node with the value "eval," it marks it as a "direct eval."


The provided Java code defines a method `_findDeserializer` that retrieves a `JsonDeserializer` for a given `typeId` from a cache. If the deserializer is not found, it attempts to resolve the type using an `_idResolver`, and if that fails, it handles unknown type IDs and retrieves a contextual deserializer. Finally, it caches the found deserializer for future use.


The provided Java code defines a static method `escape` that processes a given string to escape special characters for HTML output, based on specified output settings. It normalizes whitespace, handles character encoding, and replaces specific characters (like `<`, `>`, `&`, and `"`) with their corresponding HTML entities or numeric character references. The method uses a `StringBuilder` to accumulate the escaped output while considering whether the context is within an attribute or normal text.


The provided Java code defines a method `parseAttribute()` that parses an attribute from a token queue (`tq`). It consumes whitespace, retrieves an attribute key, and then checks for an associated value, which can be enclosed in single or double quotes or be unquoted. If a valid key is found, it returns an `Attribute` object created from the key and value; otherwise, it advances the queue if no value is present and returns null.


The provided Java code defines a method `applyPaxHeadersToCurrentEntry` that takes a map of headers and updates the properties of a `currEntry` object based on the key-value pairs in the map. It checks for specific keys such as "path", "linkpath", "gid", "gname", "uid", "uname", "size", "mtime", and certain "SCHILY" keys, and sets corresponding attributes of `currEntry` by parsing the values as needed. The method effectively populates the `currEntry` with metadata from the provided headers.


The provided Java code defines a method `declareArguments` that processes the parameters of a function node in an abstract syntax tree (AST). It retrieves the function's parameters and their associated JSDoc types, then iterates through the parameters to define slots for each, either using the JSDoc type if available or marking them as undefined. The method ensures that each parameter is appropriately handled based on the presence of type information.


The provided Java code defines a method `isSafeReplacement` that checks if a given `replacement` node can safely replace a specified `node`. It first verifies if the `node` is a name; if not, it traverses through its children until it finds a name. Finally, it checks if the name is assigned to the `replacement`, returning `false` if it is, and `true` otherwise.


The provided Java code defines a method `updateBounds` that updates the indices of minimum and maximum start, middle, and end times based on a given `TimePeriod` and its index. It compares the start and end times of the provided period with those of existing data items to determine if the current period's indices should be updated. The method ensures that the indices reflect the bounds of the time periods being processed.


The provided Java code defines an `equals` method that checks for equality between the current object and another object `o`. It first checks if both references point to the same object, then verifies if `o` is not null and is of the same class. Finally, it compares a `tag` property of the current object with that of the other object, returning true if they are equal and false otherwise.


The provided Java code defines a method `createCopy` that creates a clone of a `TimeSeries` object, copying a specified range of data items from the original series. It checks for valid start and end indices, initializes the new series with default values for minimum and maximum Y, and iterates through the specified range to clone each `TimeSeriesDataItem`, adding them to the new series. If an exception occurs during the addition of items, it is caught and printed.


The provided Java code defines a method `burstToken` that processes a command-line option token by iterating through its characters. It checks if each character corresponds to a valid option; if so, it adds the option to a list of tokens and handles any associated arguments. If a non-option character is encountered and the `stopAtNonOption` flag is set, it processes the remaining substring; otherwise, it adds the entire token to the list.


The provided Java code defines a static method `forType` that takes a `Class<?>` parameter and returns an instance of `StdKeyDeserializer` based on the type of the class. It checks for various predefined types (like `String`, `UUID`, `Integer`, etc.) and assigns a corresponding kind identifier. For specific types like `Locale` and `Currency`, it retrieves a deserializer and creates a `StdKeyDeserializer` with that deserializer, while returning `null` for unsupported types.


The provided Java code implements a Cholesky decomposition for a given square matrix, checking for symmetry and positive definiteness based on specified thresholds. It first verifies that the matrix is square and symmetric, then checks that the diagonal elements are positive before performing the decomposition. If any of these conditions are violated, it throws appropriate exceptions.


The provided Java code defines a method `parseArguments` that processes command-line parameters. It attempts to retrieve the first parameter from a `Parameters` object; if no parameter is found, it defaults to adding a value of `true`. If a parameter is present, it checks if it matches predefined "true" or "false" values (stored in `TRUES` and `FALSES` sets) and adds the corresponding boolean value to a `setter`, returning 1 if a valid parameter is processed or 0 otherwise.


The provided Java method `getTextBuffer()` returns a character array based on several conditions. It first checks if `_inputStart` is non-negative, returning `_inputBuffer` if true. If not, it checks for the presence of `_resultArray`, `_resultString`, or `_currentSegment`, returning the appropriate array or converting `_resultString` to a character array if necessary, and defaults to calling `contentsAsArray()` if none of the conditions are met.


The provided Java code defines a method `registerTypeVariablesOn` that registers type variables from a given `ParameterizedType` into a map called `contextualActualTypeParameters`. It checks if the input `classType` is a `ParameterizedType`, retrieves its type parameters and actual type arguments, and then populates the map with the corresponding actual types, handling `WildcardType` separately by storing its bounds. The method effectively associates type parameters with their actual types for further processing.


The provided Java code defines a method `hasClass` that checks if a specified class name exists within a string of class attributes, ignoring case. It first retrieves the class attribute string and compares its length with the desired class name. The method then iterates through the class attribute string, checking for matches against the specified class name, considering whitespace as delimiters between class names.


The provided Java code defines a method `extractMultilineTextualBlock` that processes a stream of JSDoc tokens to extract a multiline text block based on specified whitespace options. It builds a string from the tokens, handling line breaks and leading/trailing whitespace according to the given `WhitespaceOption`. The method returns an `ExtractionInfo` object containing the extracted text and the last processed token.
