Method Detail

getOperatorId

public int getOperatorId()

createOperator

public Operator createOperator(DriverContext driverContext)

Specified by:

createOperator in interface OperatorFactory

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 interface OperatorFactory

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 interface OperatorFactory

duplicate

public OperatorFactory duplicate()

Specified by:

duplicate in interface OperatorFactory

createOuterOperatorFactory

public Optional<JoinOperatorFactory.OuterOperatorFactoryResult> createOuterOperatorFactory()

Specified by:

createOuterOperatorFactory in interface JoinOperatorFactory
