com.lmax.disruptor

类 WorkProcessorExt<T>

java.lang.Object

com.lmax.disruptor.WorkProcessorExt<T>

类型参数:

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

所有已实现的接口:

com.lmax.disruptor.EventProcessor, java.lang.Runnable

public final class WorkProcessorExt<T>
extends java.lang.Object
implements com.lmax.disruptor.EventProcessor

因为WorkProcessor在消费者减少的时候有问题，根据后面的url，改写此类 https://github.com/LMAX-Exchange/disruptor/pull/287/files

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

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

WorkProcessorExt

public WorkProcessorExt(com.lmax.disruptor.RingBuffer<T> ringBuffer,
                        com.lmax.disruptor.SequenceBarrier sequenceBarrier,
                        com.lmax.disruptor.WorkHandler<? super T> workHandler,
                        com.lmax.disruptor.ExceptionHandler<? super T> exceptionHandler,
                        com.lmax.disruptor.Sequence workSequence)

Construct a WorkProcessorExt.

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

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

指定者:

run 在接口中 java.lang.Runnable

抛出:

java.lang.IllegalStateException - if this processor is already running
