Package org.apache.hc.core5.reactor

Event driven network communication APIs and components loosely based on Doug Lea's reactor pattern.

Interface Summary

Interface	Description
Command	Abstract command IOSession can act upon.
ConnectionAcceptor	Non-blocking connection acceptor.
ConnectionInitiator	Non-blocking connection initiator.
IOEventHandler	IOEventHandler interface is used by I/O reactors to handle I/O events for individual I/O sessions.
IOEventHandlerFactory	Factory interface to create IOEventHandler instances for the given connected endpoints.
IOReactor	HttpCore NIO is based on the Reactor pattern as described by Doug Lea.
IOReactorMetricsListener	A listener interface for receiving metrics related to the I/O reactor's thread pool performance and status.
IOReactorService	IOReactor running as a service.
IOSession	IOSession interface represents a sequence of logically related data exchanges between two end points.
IOSessionListener	IOSession event listener.
IOWorkerSelector
IOWorkerStats	Internal I/O dispatch stats that can be used by IOWorkerSelector to select the best suited worker to get new I/O channels.
ListenerEndpoint	ListenerEndpoint interface represents an endpoint used by an I/O reactor to listen for incoming connection from remote clients.
ProtocolIOSession	TLS capable, protocol upgradable IOSession.
ProtocolUpgradeHandler	Application protocol upgrade handler.

DefaultConnectingIOReactor	Multi-core I/O reactor that can act as ConnectionInitiator Internally this I/O reactor distributes newly created I/O session equally across multiple I/O worker threads for a more optimal resource utilization and a better I/O performance.
DefaultListeningIOReactor	Multi-core I/O reactor that can act as both ConnectionInitiator and ConnectionAcceptor.
EndpointParameters	Endpoint initialization parameters
EventMask	Type of I/O event notifications I/O sessions can declare interest in.

Enum Summary

Enum	Description
Command.Priority
IOReactorStatus	IOReactorStatus represents an internal status of an I/O reactor.
IOSession.Status	This enum represents a set of states I/O session transitions through during its life-span.

Exception Summary

Exception	Description
IOReactorShutdownException	Signals the I/O reactor has been shut down or is in the process of shutting down.
