Interface Summary

Interface	Description
DeadlineTimerWheel.TimerConsumer	Consumer of timer entries as deadline to timerId.
DeadlineTimerWheel.TimerHandler	Handler for processing expired timers.
DelegatingErrorHandler	ErrorHandler that can insert into a chain of responsibility so it handles an error and then delegates on to the next in the chain.
DirectBuffer	Abstraction over a range of buffer types that allows fields to be read in native typed fashion.
ErrorHandler	Callback interface for handling an error/exception that has occurred when processing an operation or event.
ExpandableRingBuffer.MessageConsumer	Consumers of messages implement this interface and pass it to ExpandableRingBuffer.consume(MessageConsumer, int).
ManagedResource	Implementations of this interface can a resource that need to have external state tracked for deletion.
MutableDirectBuffer	Abstraction over a range of buffer types that allows fields to be written in native typed fashion.
