Interface EventReceiver

All Superinterfaces:

Fiber, InitializableFiber

All Known Implementing Classes:

TcpEventReceiver, UdpEventReceiver

public interface EventReceiver
extends InitializableFiber

This interface defines the contract that every type of adaptor event receiver must fulfill. Every receiver is a fiber and will run independently of other receivers in the system. When an event is received by an instance of this interface it will pass the new event to the EventHandler.event() method.
