waitFor(long, Sequence, Sequence, SequenceBarrier) - Method in class com.lmax.disruptor.BlockingWaitStrategy

waitFor(long, Sequence, Sequence, SequenceBarrier) - Method in class com.lmax.disruptor.BusySpinWaitStrategy

waitFor(long, Sequence, Sequence, SequenceBarrier) - Method in class com.lmax.disruptor.PhasedBackoffWaitStrategy

waitFor(long) - Method in interface com.lmax.disruptor.SequenceBarrier

Wait for the given sequence to be available for consumption.

waitFor(long, Sequence, Sequence, SequenceBarrier) - Method in class com.lmax.disruptor.SleepingWaitStrategy

waitFor(long, Sequence, Sequence, SequenceBarrier) - Method in class com.lmax.disruptor.TimeoutBlockingWaitStrategy

waitFor(long, Sequence, Sequence, SequenceBarrier) - Method in interface com.lmax.disruptor.WaitStrategy

Wait for the given sequence to be available.

waitFor(long, Sequence, Sequence, SequenceBarrier) - Method in class com.lmax.disruptor.YieldingWaitStrategy

WaitStrategy - Interface in com.lmax.disruptor

Strategy employed for making EventProcessors wait on a cursor Sequence.

with(ExceptionHandler) - Method in class com.lmax.disruptor.dsl.ExceptionHandlerSetting

Specify the ExceptionHandler to use with the event handler.

withLock(long, long, TimeUnit) - Static method in class com.lmax.disruptor.PhasedBackoffWaitStrategy

Block with wait/notifyAll semantics

withSleep(long, long, TimeUnit) - Static method in class com.lmax.disruptor.PhasedBackoffWaitStrategy

Block by sleeping in a loop

WorkerPool<T> - Class in com.lmax.disruptor

WorkerPool contains a pool of WorkProcessors that will consume sequences so jobs can be farmed out across a pool of workers.

WorkerPool(RingBuffer<T>, SequenceBarrier, ExceptionHandler, WorkHandler<T>...) - Constructor for class com.lmax.disruptor.WorkerPool

Create a worker pool to enable an array of WorkHandlers to consume published sequences.

WorkerPool(EventFactory<T>, ExceptionHandler, WorkHandler<T>...) - Constructor for class com.lmax.disruptor.WorkerPool

Construct a work pool with an internal RingBuffer for convenience.

WorkHandler<T> - Interface in com.lmax.disruptor

Callback interface to be implemented for processing units of work as they become available in the RingBuffer.

WorkProcessor<T> - Class in com.lmax.disruptor

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

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

WorkProcessor(RingBuffer<T>, SequenceBarrier, WorkHandler<T>, ExceptionHandler, Sequence) - Constructor for class com.lmax.disruptor.WorkProcessor

Construct a WorkProcessor.

Y

YieldingWaitStrategy - Class in com.lmax.disruptor

Yielding strategy that uses a Thread.yield() for EventProcessors waiting on a barrier after an initially spinning.

YieldingWaitStrategy() - Constructor for class com.lmax.disruptor.YieldingWaitStrategy
