| <p>Tokenize expression. This function is equivalent to C strtok. Input sequence is split into tokens, separated by separators. Separators are given by means of the predicate.</p> |
| <p>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 <code class="computeroutput">std::vector<std::string></code> or <code class="computeroutput">std::list<boost::iterator_range<std::string::iterator>></code> </p> |
