接口 SingleSessionIoHandler

所有已知实现类:

SingleSessionIoHandlerAdapter

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.

sessionClosed

void sessionClosed()
                   throws java.lang.Exception

Invoked when the connection is closed. This method is not invoked if the transport type is UDP.

抛出:
