从接口复制的说明: WaitStrategy

Wait for the given sequence to be available. It is possible for this method to return a value less than the sequence number supplied depending on the implementation of the WaitStrategy. A common use for this is to signal a timeout. Any EventProcessor that is using a WaitStrategy to get notifications about message becoming available should remember to handle this case. The BatchEventProcessor explicitly handles this case and will signal a timeout if required.

指定者:

waitFor 在接口中 WaitStrategy

参数:

sequence - to be waited on.

cursorSequence - the main sequence from ringbuffer. Wait/notify strategies will need this as it's the only sequence that is also notified upon update.

dependentSequence - on which to wait.

barrier - the processor is waiting on.

返回:

the sequence that is available which may be greater than the requested sequence.

抛出:

AlertException - if the status of the Disruptor has changed.

InterruptedException - if the thread is interrupted.

TimeoutException - TimeoutException

signalAllWhenBlocking

public void signalAllWhenBlocking()

从接口复制的说明: WaitStrategy

Implementations should signal the waiting EventProcessors that the cursor has advanced.

指定者:

signalAllWhenBlocking 在接口中 WaitStrategy

toString

public String toString()

覆盖:

toString 在类中 Object
