addStateChangeListener

public void addStateChangeListener(StateMachine.StateChangeListener<QueryState> stateChangeListener)

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. Additionally, it is possible notifications are observed out of order due to the asynchronous execution.

addQueryInfoStateChangeListener

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

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.
