| <pre>public interface <span class="typeNameLabel">HashTreeTraverser</span></pre> |
| <div class="block">By implementing this interface, a class can easily traverse a HashTree |
| object, and be notified via callbacks of certain events. There are three such |
| events: |
| <ol> |
| <li>When a node is first encountered, the traverser's |
| <a href="../../../../org/apache/jorphan/collections/HashTreeTraverser.html#addNode-java.lang.Object-org.apache.jorphan.collections.HashTree-"><code>addNode(Object,HashTree)</code></a> method is called. It is handed the object |
| at that node, and the entire sub-tree of the node.</li> |
| <li>When a leaf node is encountered, the traverser is notified that a full |
| path has been finished via the <a href="../../../../org/apache/jorphan/collections/HashTreeTraverser.html#processPath--"><code>processPath()</code></a> method. It is the |
| traversing class's responsibility to know the path that has just finished |
| (this can be done by keeping a simple stack of all added nodes).</li> |
| <li>When a node is retraced, the traverser's <a href="../../../../org/apache/jorphan/collections/HashTreeTraverser.html#subtractNode--"><code>subtractNode()</code></a> is |
| called. Again, it is the traverser's responsibility to know which node has |
| been retraced.</li> |
| </ol> |
| To summarize, as the traversal goes down a tree path, nodes are added. When |
| the end of the path is reached, the <a href="../../../../org/apache/jorphan/collections/HashTreeTraverser.html#processPath--"><code>processPath()</code></a> call is sent. As |
| the traversal backs up, nodes are subtracted. |
| <p> |
| The traversal is a depth-first traversal.</div> |
