Constructor Detail

DecomposedQueueMainProcessingUnit

public DecomposedQueueMainProcessingUnit(String name,
                                         SpongeEngine engine,
                                         EventQueue inQueue,
                                         EventQueue outQueue)

Creates a new main processing unit.

Parameters:

name - name.

engine - the engine.

inQueue - input queue.

outQueue - output queue.

Method Detail

setDecomposedQueue

public void setDecomposedQueue(DecomposedQueue<EventProcessorAdapter<?>> decomposedQueue)

doStartup

public void doStartup()

Starts up this managed entity.

Overrides:

doStartup in class BaseEngineModule

doShutdown

public void doShutdown()

Overrides:

doShutdown in class BaseEngineModule

createWorker

public Runnable createWorker()

Creates the worker.

Returns:

the worker.

supportsControlEventForProcessor
