noMoreOperators

public void noMoreOperators()

Description copied from interface: OperatorFactory

Declare that createOperator will not be called any more and release any resources associated with this factory.

This method will be called only once. Implementation doesn't need to worry about duplicate invocations.

It is guaranteed that this will only be invoked after OperatorFactory.noMoreOperators(Lifespan) has been invoked for all applicable driver groups.

noMoreOperators in interface OperatorFactory
