Foam::expression::Result
Foam::expression::ResultIterable
Description
Class which provides the types returned by expression evaluations. This
must be specialised for expressionable containers.
In the case of iterable containers that specialisation can inherit generic
definitions from the ResultIterable class (also defined in this file).
Non-iterable containers must implement their own result classes. This is
likely to be straightforward as non-iterable containers are typically just
wrappings or structured collections of iterable containers, so the
non-iterable implementation can just wrap the types provided by the
iterable classes.
