类 WorkProcessor<T>

java.lang.Object

com.alipay.disruptor.WorkProcessor<T>

类型参数:

T - event implementation storing the details for the work to processed.

所有已实现的接口:

EventProcessor, Runnable

public final class WorkProcessor<T>
extends Object
implements EventProcessor

A WorkProcessor wraps a single WorkHandler, effectively consuming the sequence and ensuring appropriate barriers.

Generally, this will be used as part of a WorkerPool.

构造器详细资料

WorkProcessor

public WorkProcessor(RingBuffer<T> ringBuffer,
             SequenceBarrier sequenceBarrier,
             WorkHandler<? super T> workHandler,
             ExceptionHandler<? super T> exceptionHandler,
             Sequence workSequence)

Construct a WorkProcessor.

参数:

ringBuffer - to which events are published.

sequenceBarrier - on which it is waiting.

workHandler - is the delegate to which events are dispatched.

exceptionHandler - to be called back when an error occurs

workSequence - from which to claim the next event to be worked on. It should always be initialised as Sequencer.INITIAL_CURSOR_VALUE

方法详细资料

getSequence

public Sequence getSequence()

从接口复制的说明: EventProcessor

Get a reference to the Sequence being used by this EventProcessor.

指定者:

getSequence 在接口中 EventProcessor

返回:

reference to the Sequence for this EventProcessor

halt

public void halt()

从接口复制的说明: EventProcessor

Signal that this EventProcessor should stop when it has finished consuming at the next clean break. It will call SequenceBarrier.alert() to notify the thread to check status.

指定者:

halt 在接口中 EventProcessor

isRunning

public boolean isRunning()

指定者:

isRunning 在接口中 EventProcessor

run

public void run()

It is ok to have another thread re-run this method after a halt().

指定者:

run 在接口中 Runnable

抛出:

IllegalStateException - if this processor is already running
