Interface Summary

Interface	Description
Agent
AtomicBuffer	Abstraction over a range of buffer types that allows type to be accessed with memory ordering semantics.
EpochClock	Retrieves the number of milliseconds since 1 Jan 1970 UTC.
IdleStrategy	Idle strategy for use by threads when they do not have work to do.
MessageHandler	Callback interface for processing of messages that are read from a buffer.
NanoClock	Functional interface for return the current time as system wide monotonic tick of 1 nanosecond precision.
Pipe<E>	A container for items processed in sequence
QueuedPipe<E>	Composed interface for concurrent queues and sequenced containers.
RecordBuffer.RecordHandler	Callback interface for reading elements out of the buffer.
RecordBuffer.RecordWriter	Interface for safely writing to the buffer.

Class Summary

Class	Description
AbstractConcurrentArrayQueue<E>	Left over immutable queue fields.
AgentRunner	Base agent runner that is responsible for lifecycle of an Agent and ensuring exceptions are handled.
BackoffIdleStrategy
BusySpinIdleStrategy	Busy spin strategy targeted at lowest possible latency.
CompositeAgent	Compose several agents into one so a thread can be shared.
ControllableIdleStrategy
HighResolutionTimer	Control the supporting of high resolution timers for scheduled events by enabling the MidiDevice.
ManyToManyConcurrentArrayQueue<E>	Many producer to many consumer concurrent queue that is array backed.
ManyToOneConcurrentArrayQueue<E>	Many producer to one consumer concurrent queue that is array backed.
ManyToOneConcurrentLinkedQueue<E>	Concurrent linked Queue that can be used from many producers and a single consumer.
MappedResizeableBuffer	Supports regular, byte ordered, and atomic (memory ordered) access to an underlying buffer.
NoOpIdleStrategy	Low-latency idle strategy to be employed in loops that do significant work on each iteration such that any work in the idle strategy would be wasteful.
OneToOneConcurrentArrayQueue<E>	One producer to one consumer concurrent queue that is array backed.
RecordBuffer	A record buffer is an off-heap buffer with a series of records and a header that can be written to or read from multiple threads.
SigInt	Utility to allow the registration of a SIGINT handler that hides the unsupported Signal class.
SigIntBarrier	One time barrier for blocking a thread until a SIGINT signal is received from the operating system.
SleepingIdleStrategy	When idle this strategy is to sleep for a specified period.
SystemEpochClock	Implementation that calls System.currentTimeMillis().
SystemNanoClock	A NanoClock the delegates to System.nanoTime().
UnsafeBuffer	Supports regular, byte ordered, and atomic (memory ordered) access to an underlying buffer.
YieldingIdleStrategy	IdleStrategy that will call Thread.yield() when the work count is zero.
