createOperator in interface OperatorFactorypublic void noMoreOperators()
OperatorFactoryThis 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.
