Interface SingleSessionIoHandler

All Known Implementing Classes:

SingleSessionIoHandlerAdapter

@Deprecated
public interface SingleSessionIoHandler

Deprecated.

This class is not to be used anymore

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.

Method Detail

sessionCreated

void sessionCreated()
             throws Exception

Deprecated.

Invoked when the session is created. Initialize default socket parameters and user-defined attributes here.

Throws:

Exception - If the session can't be created

See Also:

IoHandler.sessionCreated(IoSession)

sessionOpened

void sessionOpened()
            throws Exception

Deprecated.

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

Throws:

Exception - If the session can't be opened

See Also:

IoHandler.sessionOpened(IoSession)

sessionClosed

void sessionClosed()
            throws Exception

Deprecated.

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

Throws:

Exception - If the session can't be closed

See Also:

IoHandler.sessionClosed(IoSession)

sessionIdle

void sessionIdle(IdleStatus status)
          throws Exception

Deprecated.

Invoked when the connection is idle. Refer to IdleStatus. This method is not invoked if the transport type is UDP.

Parameters:

status - the type of idleness

Throws:

Exception - If the idle event can't be handled

See Also:

IoHandler.sessionIdle(IoSession, IdleStatus)

exceptionCaught

void exceptionCaught(Throwable cause)
              throws Exception

Deprecated.

Invoked when any exception is thrown by user IoHandler implementation or by MINA. If cause is instanceof IOException, MINA will close the connection automatically.

Parameters:

cause - the caught exception

Throws:

Exception - If the exception can't be handled

See Also:

IoHandler.exceptionCaught(IoSession, Throwable)

inputClosed

void inputClosed(IoSession session)

Deprecated.

Invoked when a half-duplex connection is closed

Parameters:

session - The current session

messageReceived

void messageReceived(Object message)
              throws Exception

Deprecated.

Invoked when protocol message is received. Implement your protocol flow here.

Parameters:

message - the received message

Throws:

Exception - If the received message can't be processed

See Also:

IoHandler.messageReceived(IoSession, Object)

messageSent

void messageSent(Object message)
          throws Exception

Deprecated.

Invoked when protocol message that user requested by IoSession.write(Object) is sent out actually.

Parameters:

message - the sent message

Throws:

Exception - If the sent message can't be processed

See Also:

IoHandler.messageSent(IoSession, Object)

event

void event(FilterEvent event)
    throws Exception

Deprecated.

Invoked when a filter event is fired. Each filter might sent a different event, this is very application specific.

Parameters:

event - The event to process

Throws:

Exception - If we get an exception while processing the event
