Examples of NodeListener

The interface must be used by handlers that are appended to NodeKeeper. The generic type for the listener must be handled by a DataHandler

A listener that can be registered with the {@link WatchdogService}to be notified of node status change events. Invocations to the methods of a {@code NodeListener} are made outside of atransaction.
The implementations for the methods of this interface should be idempotent because they may be invoked multiple times. However, for any given node, the {@link #nodeStarted nodeStarted} methodwill never be invoked after the {@link #nodeFailed nodeFailed}method is invoked for that given node. @see WatchdogService#addNodeListener(NodeListener)
