<hr><a name="_details"></a><h2>Detailed Description</h2>
<a class="el" href="classUnicodeSetIterator.html">UnicodeSetIterator</a> iterates over the contents of a <a class="el" href="classUnicodeSet.html">UnicodeSet</a>.
<p>
It iterates over either code points or code point ranges. After all code points or ranges have been returned, it returns the multicharacter strings of the UnicodSet, if any.<p>
This class is not intended to be subclassed. Consider any fields or methods declared as "protected" to be private. The use of protected in this class is an artifact of history.<p>
To iterate over code points and strings, use a loop like this: <pre>
<a class="el" href="classUnicodeSetIterator.html">UnicodeSetIterator</a> it(set);
while (set.next()) {
processItem(set.getString());
}
</pre> <p>
Each item in the set is accessed as a string. Set elements consisting of single code points are returned as strings containing just the one code point.<p>
To iterate over code point ranges, instead of individual code points, use a loop like this: <pre>
<a class="el" href="classUnicodeSetIterator.html">UnicodeSetIterator</a> it(set);
while (it.nextRange()) {
if (it.isString()) {
processString(it.getString());
} else {
processCodepointRange(it.getCodepoint(), it.getCodepointEnd());
}
}
