addStateChangeListener

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

Description copied from interface: ManagedQueryExecution

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.

Specified by:

addStateChangeListener in interface ManagedQueryExecution

startWaitingForResources

public void startWaitingForResources()

Specified by:

startWaitingForResources in interface ManagedQueryExecution

fail

public void fail(Throwable throwable)

Specified by:

fail in interface ManagedQueryExecution

Specified by:

fail in interface QueryTracker.TrackedQuery

cancel

public void cancel()

Specified by:

cancel in interface DispatchQuery
