public void noMoreOperators(Lifespan lifespan)

Description copied from interface: OperatorFactory

Declare that createOperator will not be called any more for the specified Lifespan, and release any resources associated with this factory.

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

It is guaranteed that this method will be invoked for all applicable driver groups before OperatorFactory.noMoreOperators() is invoked.
