<p>A concrete subclass of <a class="el" href="classCharacterIterator.html" title="Abstract class that defines an API for iteration on text objects.">CharacterIterator</a> that iterates over the characters (code units or code points) in a UChar array. </p>
<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). </p>
