///Usage
///-----
// This section illustrates intended use of this component.
//
///Example 1: Basic 'bdlt::Iso8601Util' Usage
/// - - - - - - - - - - - - - - - - - - - - -
// This example demonstrates basic use of one 'generate' function and two
// 'parse' functions.
//
// First, we construct a few objects that are prerequisites for this and the
// following example:
//..
const bdlt::Date date(2005, 1, 31); // 2005/01/31
const bdlt::Time time(8, 59, 59, 123); // 08:59:59.123
const int tzOffset = 240; // +04:00 (four hours west of UTC)
//..
// Then, we construct a 'bdlt::DatetimeTz' object for which a corresponding ISO
// 8601-compliant string will be generated shortly:
//..
const bdlt::DatetimeTz sourceDatetimeTz(bdlt::Datetime(date, time),
tzOffset);
//..
// For comparison with the ISO 8601 string generated below, note that streaming
// the value of 'sourceDatetimeTz' to 'stdout':
//..
if (veryVerbose)
bsl::cout << sourceDatetimeTz << bsl::endl;
//..
// produces:
//..
// 31JAN2005_08:59:59.123000+0400
//..
// Next, we use a 'generate' function to produce an ISO 8601-compliant string
// for 'sourceDatetimeTz', writing the output to a 'bsl::ostringstream', and
// assert that both the return value and the string that is produced are as
// expected:
//..
bsl::ostringstream oss;
const bsl::ostream& ret =
bdlt::Iso8601Util::generate(oss, sourceDatetimeTz);
ASSERT(&oss == &ret);
const bsl::string iso8601 = oss.str();
ASSERT(iso8601 == "2005-01-31T08:59:59.123+04:00");
//..
// For comparison, see the output that was produced by the streaming operator
// above.
//
// Now, we parse the string that was just produced, loading the result of the
// parse into a second 'bdlt::DatetimeTz' object, and assert that the parse was
// successful and that the target object has the same value as that of the
// original (i.e., 'sourceDatetimeTz'):
//..
bdlt::DatetimeTz targetDatetimeTz;
int rc = bdlt::Iso8601Util::parse(&targetDatetimeTz,
iso8601.c_str(),
static_cast<int>(iso8601.length()));
ASSERT( 0 == rc);
ASSERT(sourceDatetimeTz == targetDatetimeTz);
//..
// Finally, we parse the 'iso8601' string a second time, this time loading the
// result into a 'bdlt::Datetime' object (instead of a 'bdlt::DatetimeTz'):
//..
bdlt::Datetime targetDatetime;
rc = bdlt::Iso8601Util::parse(&targetDatetime,
iso8601.c_str(),
static_cast<int>(iso8601.length()));
ASSERT( 0 == rc);
