<div class="block">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
StringBuilder objects, you can use the SearchByClass traverser to find all
the StringBuilder objects in your tree.
<p>
Usage is simple. Given a <a href="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(StringBuilder.class);
tree.traverse(searcher);
Iterator iter = searcher.getSearchResults().iterator();
while (iter.hasNext()) {
StringBuilder foundNode = (StringBuilder) iter.next();
HashTree subTreeOfFoundNode = searcher.getSubTree(foundNode);
// .... do something with node and subTree...
