Methods

Modifier and Type	Method and Description
static <IN,OUT> InvocationFactory<IN,OUT>	factoryFrom(Routine<IN,OUT> routine, DelegatingInvocation.DelegationType delegation) Returns a factory of delegating invocations.
void	onAbort(RoutineException reason) Called when the routine execution is aborted. This method may be called at any time after the invocation initialization.
void	onDestroy() Called when the routine invocation is no longer needed.
void	onInitialize() Called when the routine invocation is initialized. This is always the first method in the invocation lifecycle.
void	onInput(IN input, ResultChannel<OUT> result) Called when an input is passed to the routine. This method is called once for each input object.
void	onResult(ResultChannel<OUT> result) Called when all the inputs has been passed to the routine. This method is called once in the invocation lifecycle to indicate that the final invocation results should be passed to the result channel.
void	onTerminate() Called when the invocation execution has completed.
