Method Summary

void	recover(Node node, SimpleCompletionHandler handler) Notifies this listener that the specified node has failed and that this listener needs to orchestrate recovery.

Method Detail

recover

void recover(Node node,
             SimpleCompletionHandler handler)

Notifies this listener that the specified node has failed and that this listener needs to orchestrate recovery. This method is invoked outside of a transaction.

When recovery for this listener for the specified node is complete, the completed method of the specified handler must be invoked.

Recovery does not need to be performed in this method, but may be performed asynchronously.

The implementation of this method should be idempotent because it may be invoked multiple times. If it is invoked multiple times, the completed method must be called for each handler provided.

Parameters:

node - a failed node to recover

handler - a handler to notify when recovery is complete
