<a name="idm45555124631856"></a><h2>Description</h2>
<p>Split iterator encapsulates a Finder and allows for incremental searching in a string. Unlike the find iterator, split iterator iterates through gaps between matches.</p>
<p>Find iterator is a readable forward traversal iterator.</p>
<p>Dereferencing the iterator yields an iterator_range delimiting the current match. </p>
