Method Summary

Modifier and Type	Method and Description
OutputRateLimiter	clone(String key)
Map<String,Object>	currentState() Used to collect the serializable state of the processing element, that need to be persisted for the reconstructing the element to the same state on a different point of time
void	process(ComplexEventChunk complexEventChunk)
void	restoreState(Map<String,Object> state) Used to restore serialized state of the processing element, for reconstructing the element to the same state as if was on a previous point of time.
void	start() This will be called only once and this can be used to acquire required resources for the processing element.
void	stop() This will be called only once and this can be used to release the acquired resources for processing.

AllPerEventOutputRateLimiter

public AllPerEventOutputRateLimiter(String id,
                                    Integer value)

Method Detail

clone

public OutputRateLimiter clone(String key)

Specified by:

clone in class OutputRateLimiter

process

public void process(ComplexEventChunk complexEventChunk)

Specified by:

process in class OutputRateLimiter

start

public void start()

Description copied from interface: EternalReferencedHolder

This will be called only once and this can be used to acquire required resources for the processing element. This will be called after initializing the system and before starting to process the events.

stop

public void stop()

Description copied from interface: EternalReferencedHolder

This will be called only once and this can be used to release the acquired resources for processing. This will be called before shutting down the system.

Description copied from interface: Snapshotable

Used to collect the serializable state of the processing element, that need to be persisted for the reconstructing the element to the same state on a different point of time

Returns:

stateful objects of the processing element as an array

restoreState

public void restoreState(Map<String,Object> state)

Description copied from interface: Snapshotable

Used to restore serialized state of the processing element, for reconstructing the element to the same state as if was on a previous point of time.

Parameters:

state - the stateful objects of the element as an array on the same order provided by currentState().
