IDispatchable.Poll
Method
Visual Basic
Function Poll () As Boolean
C#
bool Poll ();
Purpose
Dispatch an event, if possible.
Remarks
If an event is ready to dispatch, then this call dispatches it, and then returns. If no events are waiting, then this call returns immediately.
When the call dispatches an event, it returns true. When the call does not dispatch an event, it returns false.
This call is equivalent to timedDispatch(TimeoutValue.NoWait).
Both Queue and QueueGroup implement this method.
