<hr/><a name="details" id="details"></a><h2>Detailed Description</h2>
<div class="textblock"><p>Abstract class that defines an API for iteration on text objects. </p>
<p>This is an interface for forward and backward iteration and random access into a text object.</p>
<p>The API provides backward compatibility to the Java and older ICU <a class="el" href="classCharacterIterator.html" title="Abstract class that defines an API for iteration on text objects.">CharacterIterator</a> classes but extends them significantly: </p>
<ol>
<li>
<a class="el" href="classCharacterIterator.html" title="Abstract class that defines an API for iteration on text objects.">CharacterIterator</a> is now a subclass of <a class="el" href="classForwardCharacterIterator.html" title="Abstract class that defines an API for forward-only iteration on text objects.">ForwardCharacterIterator</a>. </li>
<li>
While the old API functions provided forward iteration with "pre-increment" semantics, the new one also provides functions with "post-increment" semantics. They are more efficient and should be the preferred iterator functions for new implementations. The backward iteration always had "pre-decrement" semantics, which are efficient. </li>
<li>
Just like <a class="el" href="classForwardCharacterIterator.html" title="Abstract class that defines an API for forward-only iteration on text objects.">ForwardCharacterIterator</a>, it provides access to both code units and code points. Code point access versions are available for the old and the new iteration semantics. </li>
<li>
There are new functions for setting and moving the current position without returning a character, for efficiency. </li>
</ol>
<p>See <a class="el" href="classForwardCharacterIterator.html" title="Abstract class that defines an API for forward-only iteration on text objects.">ForwardCharacterIterator</a> for examples for using the new forward iteration functions. For backward iteration, there is also a <a class="el" href="classCharacterIterator.html#a785a86ae2f1730806eef19595f14d1aa" title="Returns FALSE if there are no more code units or code points before the current position in the itera...">hasPrevious()</a> function that can be used analogously to <a class="el" href="classForwardCharacterIterator.html#ab53c28ee0b9ff659983ded76e53f6251" title="Returns FALSE if there are no more code units or code points at or after the current position in the ...">hasNext()</a>. The old functions work as before and are shown below.</p>
<p>Examples for some of the new functions:</p>
