Method Detail

getMessage

public java.lang.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:

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 java.lang.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

                 throws java.lang.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:

java.lang.InterruptedException

awaitUninterruptibly

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:
