Defines basic split algorithms.
|
|
Split algorithms can be used to divide a string
|
|
into several parts according to given criteria.
|
|
|
|
Each part is copied and added as a new element to the
|
|
output container.
|
|
Thus the result container must be able to hold copies
|
|
of the matches (in a compatible structure like std::string) or
|
|
a reference to it (e.g. using the iterator range class).
|
|
Examples of such a container are \c std::vector<std::string>
|
|
or \c std::list<boost::iterator_range<std::string::iterator>>
