| Provides the contract for pluggable javascript handlers. | |
| <p/> | |
| One of the main tasks the handler must perform is keeping track | |
| of which nodes changed state after the user interacted with the | |
| tree in the browser. This is also the reason why the handler | |
| extends <A HREF="../../../../../org/apache/click/extras/tree/TreeListener.html" title="interface in org.apache.click.extras.tree"><CODE>TreeListener</CODE></A> to be informed of any changes | |
| to node state via other means. | |
