public final class LiteBlockingWaitStrategy extends Object implements WaitStrategy
BlockingWaitStrategy that attempts to elide conditional wake-ups when
the lock is uncontended. Shows performance improvements on microbenchmarks. However this
wait strategy should be considered experimental as I have not full proved the correctness of
the lock elision code.| 构造器和说明 |

WaitStrategyBatchEventProcessor explicitly
handles this case and will signal a timeout if required.waitFor 在接口中 WaitStrategysequence - 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.AlertException - if the status of the Disruptor has changed.InterruptedException - if the thread is interrupted.public void signalAllWhenBlocking()
