IoHandlerAdapter

public IoHandlerAdapter()

方法详细资料

sessionCreated

public void sessionCreated(IoSession session)
                    throws java.lang.Exception

Invoked from an I/O processor thread when a new connection has been created. Because this method is supposed to be called from the same thread that handles I/O of multiple sessions, please implement this method to perform tasks that consumes minimal amount of time such as socket parameter and user-defined session attribute initialization.

指定者:

sessionCreated 在接口中 IoHandler

参数:

session - The session being created

抛出:

java.lang.Exception - If we get an exception while processing the create event

sessionOpened

public void sessionOpened(IoSession session)
                   throws java.lang.Exception

Invoked when a connection has been opened. This method is invoked after IoHandler.sessionCreated(IoSession). The biggest difference from IoHandler.sessionCreated(IoSession) is that it's invoked from other thread than an I/O processor thread once thread model is configured properly.

指定者:

sessionOpened 在接口中 IoHandler

参数:

session - The session being opened

抛出:

java.lang.Exception - If we get an exception while processing the open event

sessionClosed

public void sessionClosed(IoSession session)
                   throws java.lang.Exception

Invoked when a connection is closed.

指定者:

sessionClosed 在接口中 IoHandler

参数:

session - The session being closed

抛出:

java.lang.Exception - If we get an exception while processing the close event

sessionIdle

public void sessionIdle(IoSession session,
               IdleStatus status)
                 throws java.lang.Exception

Invoked with the related IdleStatus when a connection becomes idle. This method is not invoked if the transport type is UDP; it's a known bug, and will be fixed in 2.0.

指定者:

sessionIdle 在接口中 IoHandler

参数:

session - The idling session

status - The session's status

抛出:

java.lang.Exception - If we get an exception while processing the idle event

exceptionCaught

public void exceptionCaught(IoSession session,
                   java.lang.Throwable cause)
                     throws java.lang.Exception

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

指定者:

exceptionCaught 在接口中 IoHandler

参数:

session - The session for which we have got an exception

cause - The exception that has been caught

抛出:

java.lang.Exception - If we get an exception while processing the caught exception

messageReceived

public void messageReceived(IoSession session,
                   java.lang.Object message)
                     throws java.lang.Exception

Invoked when a message is received.

指定者:

messageReceived 在接口中 IoHandler

参数:

session - The session that is receiving a message

message - The received message

抛出:

java.lang.Exception - If we get an exception while processing the received message

messageSent

public void messageSent(IoSession session,
               java.lang.Object message)
                 throws java.lang.Exception

Invoked when a message written by IoSession.write(Object) is sent out.

指定者:

messageSent 在接口中 IoHandler

参数:

session - The session that has sent a full message

message - The sent message

抛出:

java.lang.Exception - If we get an exception while processing the sent message

inputClosed

public void inputClosed(IoSession session)
                 throws java.lang.Exception

Handle the closure of an half-duplex TCP channel

指定者:

inputClosed 在接口中 IoHandler

参数:

session - The session which input is being closed

抛出:

java.lang.Exception - If we get an exception while closing the input
