addFinalQueryInfoListener

public void addFinalQueryInfoListener(StateMachine.StateChangeListener<QueryInfo> stateChangeListener)

Description copied from interface: QueryExecution

Add a listener for the final query info. This notification is guaranteed to be fired only once. Listener is always notified asynchronously using a dedicated notification thread pool so, care should be taken to avoid leaking this when adding a listener in a constructor.

Specified by:

addFinalQueryInfoListener in interface QueryExecution
