接口概要

接口	说明
Cursored	Implementors of this interface must provide a single long value that represents their current cursor value.
DataProvider<T>
EventFactory<T>	Called by the RingBuffer to pre-populate all the events to fill the RingBuffer.
EventHandler<T>	Callback interface to be implemented for processing events as they become available in the RingBuffer
EventPoller.Handler<T>
EventProcessor	EventProcessors waitFor events to become available for consumption from the RingBuffer An EventProcessor will generally be associated with a Thread for execution.
EventReleaseAware
EventReleaser
EventSequencer<T>
EventSink<E>
EventTranslator<T>	Implementations translate (write) data representations into events claimed from the RingBuffer.
EventTranslatorOneArg<T,A>	Implementations translate another data representations into events claimed from the RingBuffer
EventTranslatorThreeArg<T,A,B,C>	Implementations translate another data representations into events claimed from the RingBuffer
EventTranslatorTwoArg<T,A,B>	Implementations translate another data representations into events claimed from the RingBuffer
EventTranslatorVararg<T>	Implementations translate another data representations into events claimed from the RingBuffer
ExceptionHandler<T>	Callback handler for uncaught exceptions in the event processing cycle of the BatchEventProcessor
LifecycleAware	Implement this interface in your EventHandler to be notified when a thread for the BatchEventProcessor starts and shuts down.
SequenceBarrier	Coordination barrier for tracking the cursor for publishers and sequence of dependent EventProcessors for processing a data structure
Sequenced
Sequencer	Coordinates claiming sequences for access to a data structure while tracking dependent Sequences
SequenceReportingEventHandler<T>	Used by the BatchEventProcessor to set a callback allowing the EventHandler to notify when it has finished consuming an event if this happens after the EventHandler.onEvent(Object, long, boolean) call.
TimeoutHandler
WaitStrategy	Strategy employed for making EventProcessors wait on a cursor Sequence.
WorkHandler<T>	Callback interface to be implemented for processing units of work as they become available in the RingBuffer.

类概要

类	说明
AbstractSequencer	Base class for the various sequencer types (single/multi).
AggregateEventHandler<T>	An aggregate collection of EventHandlers that get called in sequence for each event.
BatchEventProcessor<T>	Convenience class for handling the batching semantics of consuming entries from a RingBuffer and delegating the available events to an EventHandler.
BlockingWaitStrategy	Blocking strategy that uses a lock and condition variable for EventProcessors waiting on a barrier.
BusySpinWaitStrategy	Busy Spin strategy that uses a busy spin loop for EventProcessors waiting on a barrier.
EventPoller<T>	Experimental poll-based interface for the Disruptor.
FatalExceptionHandler	Convenience implementation of an exception handler that using standard JDK logging to log the exception as Level.SEVERE and re-throw it wrapped in a RuntimeException
FixedSequenceGroup	Hides a group of Sequences behind a single Sequence
IgnoreExceptionHandler	Convenience implementation of an exception handler that using standard JDK logging to log the exception as Level.INFO
LiteBlockingWaitStrategy	Variation of the BlockingWaitStrategy that attempts to elide conditional wake-ups when the lock is uncontended.
LiteTimeoutBlockingWaitStrategy	Variation of the TimeoutBlockingWaitStrategy that attempts to elide conditional wake-ups when the lock is uncontended.
MultiProducerSequencer	Coordinator for claiming sequences for access to a data structure while tracking dependent Sequences.
NoOpEventProcessor	No operation version of a EventProcessor that simply tracks a Sequence.
PhasedBackoffWaitStrategy	Phased wait strategy for waiting EventProcessors on a barrier.
RingBuffer<E>	Ring based store of reusable entries containing the data representing an event being exchanged between event producer and EventProcessors.
Sequence	Concurrent sequence class used for tracking the progress of the ring buffer and event processors.
SequenceGroup	A Sequence group that can dynamically have Sequences added and removed while being thread safe.
SingleProducerSequencer	Coordinator for claiming sequences for access to a data structure while tracking dependent Sequences.
SleepingWaitStrategy	Sleeping strategy that initially spins, then uses a Thread.yield(), and eventually sleep (LockSupport.parkNanos(1)) for the minimum number of nanos the OS and JVM will allow while the EventProcessors are waiting on a barrier.
TimeoutBlockingWaitStrategy
WorkerPool<T>	WorkerPool contains a pool of WorkProcessors that will consume sequences so jobs can be farmed out across a pool of workers.
WorkProcessor<T>	A WorkProcessor wraps a single WorkHandler, effectively consuming the sequence and ensuring appropriate barriers.
YieldingWaitStrategy	Yielding strategy that uses a Thread.yield() for EventProcessors waiting on a barrier after an initially spinning.

异常错误概要

异常错误	说明
AlertException	Used to alert EventProcessors waiting at a SequenceBarrier of status changes.
InsufficientCapacityException	Exception thrown when it is not possible to insert a value into the ring buffer without it wrapping the consuming sequences.
TimeoutException
