<p>Instances of <code><a class="el" href="classicu_1_1SearchIterator.html" title="SearchIterator is an abstract base class that provides methods to search for a pattern within a text ...">SearchIterator</a></code> maintain a current position and scans over the target text, returning the indices the pattern is matched and the length of each match. </p>
<p><code><a class="el" href="classicu_1_1SearchIterator.html" title="SearchIterator is an abstract base class that provides methods to search for a pattern within a text ...">SearchIterator</a></code> defines a protocol for text searching. Subclasses provide concrete implementations of various search algorithms. For example, <code><a class="el" href="classicu_1_1StringSearch.html" title="StringSearch is a SearchIterator that provides language-sensitive text searching based on the compari...">StringSearch</a></code> implements language-sensitive pattern matching based on the comparison rules defined in a <code><a class="el" href="classicu_1_1RuleBasedCollator.html" title="The RuleBasedCollator class provides the implementation of Collator, using data-driven tables...">RuleBasedCollator</a></code> object. </p>
<p>Other options for searching includes using a <a class="el" href="classicu_1_1BreakIterator.html" title="The BreakIterator class implements methods for finding the location of boundaries in text...">BreakIterator</a> to restrict the points at which matches are detected. </p>
<p><code><a class="el" href="classicu_1_1SearchIterator.html" title="SearchIterator is an abstract base class that provides methods to search for a pattern within a text ...">SearchIterator</a></code> provides an API that is similar to that of other text iteration classes such as <code><a class="el" href="classicu_1_1BreakIterator.html" title="The BreakIterator class implements methods for finding the location of boundaries in text...">BreakIterator</a></code>. Using this class, it is easy to scan through text looking for all occurances of a given pattern. The following example uses a <code><a class="el" href="classicu_1_1StringSearch.html" title="StringSearch is a SearchIterator that provides language-sensitive text searching based on the compari...">StringSearch</a></code> object to find all instances of "fox" in the target string.
