<div class="block">This class is used to create a tree structure of objects. Each element in the
 tree is also a key to the next node down in the tree. It provides many ways
 to add objects and branches, as well as many ways to retrieve.
 <p>
 HashTree implements the Map interface for convenience reasons. The main
 difference between a Map and a HashTree is that the HashTree organizes the
 data into a recursive tree structure, and provides the means to manipulate
 that structure.
 <p>
 Of special interest is the <a href="../../../../org/apache/jorphan/collections/HashTree.html#traverse-org.apache.jorphan.collections.HashTreeTraverser-"><code>traverse(HashTreeTraverser)</code></a> method, which
 provides an expedient way to traverse any HashTree by implementing the
 <a href="../../../../org/apache/jorphan/collections/HashTreeTraverser.html" title="interface in org.apache.jorphan.collections"><code>HashTreeTraverser</code></a> interface in order to perform some operation on the
 tree, or to extract information from the tree.</div>
