Method Detail

removed

void removed(EventExpression eventExpression)

This method will be called whenever this Listener is removed from an EventExpression it is attached to, or when the event expression has moved into a state where it will never match again e.g. "on A() within (10.0)" after 10 seconds have elapsed without an A(). The method should execute as quickly as possible as it will be called synchronously by the Correlator.
