ReadFuture	await() Wait for the asynchronous operation to complete.
ReadFuture	awaitUninterruptibly() Wait for the asynchronous operation to complete uninterruptibly.
Throwable	getException() Returns the cause of the read failure if and only if the read operation has failed due to an Exception.
Object	getMessage() Returns the received message.
boolean	isClosed() Returns true if the IoSession associated with this future has been closed.
boolean	isRead() Returns true if a message was received successfully.
ReadFuture	removeListener(IoFutureListener<?> listener) Removes an existing event listener so it won't be notified when the future is completed.
void	setClosed() Sets the associated IoSession is closed.

Constructor Detail

DefaultReadFuture

public DefaultReadFuture(IoSession session)

Creates a new instance.

Method Detail

getMessage

public Object getMessage()

Description copied from interface: ReadFuture

Returns the received message. It returns null if this future is not ready or the associated IoSession has been closed.

Specified by:

getMessage in interface ReadFuture

isRead

public boolean isRead()

Description copied from interface: ReadFuture

Returns true if a message was received successfully.

Specified by:

isRead in interface ReadFuture

isClosed

public boolean isClosed()

Description copied from interface: ReadFuture

Returns true if the IoSession associated with this future has been closed.

Specified by:

isClosed in interface ReadFuture

getException

public Throwable getException()

Description copied from interface: ReadFuture

Returns the cause of the read failure if and only if the read operation has failed due to an Exception. Otherwise, null is returned.

Specified by:

getException in interface ReadFuture

setClosed

public void setClosed()

Description copied from interface: ReadFuture

Sets the associated IoSession is closed. This method is invoked by MINA internally. Please do not call this method directly.

Specified by:

setClosed in interface ReadFuture

setRead

public void setRead(Object message)

Description copied from interface: ReadFuture

Sets the message is written, and notifies all threads waiting for this future. This method is invoked by MINA internally. Please do not call this method directly.

Specified by:

setRead in interface ReadFuture

setException

public void setException(Throwable exception)

Description copied from interface: ReadFuture

Sets the cause of the read failure, and notifies all threads waiting for this future. This method is invoked by MINA internally. Please do not call this method directly.

Specified by:

setException in interface ReadFuture

await

public ReadFuture await()
                 throws InterruptedException

Description copied from class: DefaultIoFuture

Wait for the asynchronous operation to complete. The attached listeners will be notified when the operation is completed.

Specified by:

await in interface IoFuture

Specified by:

await in interface ReadFuture

Overrides:

await in class DefaultIoFuture

Throws:

InterruptedException

awaitUninterruptibly

public ReadFuture awaitUninterruptibly()

Description copied from class: DefaultIoFuture

Wait for the asynchronous operation to complete uninterruptibly. The attached listeners will be notified when the operation is completed.

Specified by:

awaitUninterruptibly in interface IoFuture

Specified by:

awaitUninterruptibly in interface ReadFuture

Overrides:

awaitUninterruptibly in class DefaultIoFuture

Returns:

the current IoFuture

addListener

public ReadFuture addListener(IoFutureListener<?> listener)

Description copied from class: DefaultIoFuture

Adds an event listener which is notified when this future is completed. If the listener is added after the completion, the listener is directly notified.

Specified by:

addListener in interface IoFuture

Specified by:

addListener in interface ReadFuture

Overrides:

addListener in class DefaultIoFuture

removeListener

public ReadFuture removeListener(IoFutureListener<?> listener)

Description copied from class: DefaultIoFuture

Removes an existing event listener so it won't be notified when the future is completed.

Specified by:

removeListener in interface IoFuture

Specified by:

removeListener in interface ReadFuture

Overrides:

removeListener in class DefaultIoFuture
