<hr><a name="_details"></a><h2>Detailed Description</h2>
A concrete subclass of <a class="el" href="classCharacterIterator.html">CharacterIterator</a> that iterates over the characters (code units or code points) in a UChar array.
<p>
It's possible not only to create an iterator that iterates over an entire UChar array, but also to create one that iterates over only a subrange of a UChar array (iterators over different subranges of the same UChar array don't compare equal). <dl class="see" compact><dt><b>See also:</b></dt><dd><a class="el" href="classCharacterIterator.html">CharacterIterator</a> <p>
