createOperator
in interfaceOperatorFactory
-
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.- Specified by:
noMoreOperators
in interfaceOperatorFactory
-
noMoreOperators
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.- Specified by:
noMoreOperators
in interfaceOperatorFactory
