Interface SingleSessionIoHandler

All Known Implementing Classes:

AbstractServerConnectionHandler, ServerConnectionHandler, SingleSessionIoHandlerAdapter

Deprecated.

@Deprecated
public interface SingleSessionIoHandler

A session handler without an IoSession parameter for simplicity.

A SingleSessionIoHandler is similar to an IoHandler with the notable difference that a SingleSessionIoHandler is used only by one session at a time. Thus, there is no IoSession parameter in the methods of this interface.

Because events are passed to the session in order, it is possible to store conversational state as instance variables in this object.

WARNING: This class is badly named as the actual IoHandler implementor is in fact the SingleSessionIoHandlerDelegate.
