<P>
Useful for finding all nodes in the tree that represent objects of a
particular type. For instance, if your tree contains all strings, and a few
StringBuffer objects, you can use the SearchByClass traverser to find all the
StringBuffer objects in your tree.
<p>
Usage is simple. Given a <A HREF="../../../../org/apache/jorphan/collections/HashTree.html" title="class in org.apache.jorphan.collections"><CODE>HashTree</CODE></A> object "tree", and a SearchByClass
object:
<pre>
HashTree tree = new HashTree();
// ... tree gets filled with objects
SearchByClass searcher = new SearchByClass(StringBuffer.class);
tree.traverse(searcher);
Iterator iter = searcher.getSearchResults().iterator();
while (iter.hasNext()) {
StringBuffer foundNode = (StringBuffer) iter.next();
HashTree subTreeOfFoundNode = searcher.getSubTree(foundNode);
// .... do something with node and subTree...
}
