Constructor Summary

DefaultWriteFuture(IoSession session)
Creates a new instance.

Method Summary

WriteFuture	addListener(IoFutureListener<?> listener) Adds an event listener which is notified when this future is completed.
WriteFuture	await() Wait for the asynchronous operation to complete.
WriteFuture	awaitUninterruptibly() Wait for the asynchronous operation to complete uninterruptibly.
Throwable	getException() Returns the cause of the write failure if and only if the write operation has failed due to an Exception.
boolean	isWritten() Returns true if the write operation is finished successfully.
static WriteFuture	newNotWrittenFuture(IoSession session, Throwable cause) Returns a new DefaultWriteFuture which is already marked as 'not written'.
static WriteFuture	newWrittenFuture(IoSession session) Returns a new DefaultWriteFuture which is already marked as 'written'.
WriteFuture	removeListener(IoFutureListener<?> listener) Removes an existing event listener so it won't be notified when the future is completed.
void	setException(Throwable exception) Sets the cause of the write failure, and notifies all threads waiting for this future.
void	setWritten() Sets the message is written, and notifies all threads waiting for this future.

Constructor Detail

DefaultWriteFuture

public DefaultWriteFuture(IoSession session)

Creates a new instance.

Method Detail

newWrittenFuture

public static WriteFuture newWrittenFuture(IoSession session)

Returns a new DefaultWriteFuture which is already marked as 'written'.

newNotWrittenFuture

public static WriteFuture newNotWrittenFuture(IoSession session,
                                              Throwable cause)

Returns a new DefaultWriteFuture which is already marked as 'not written'.

isWritten

public boolean isWritten()

Returns true if the write operation is finished successfully.

Specified by:

isWritten in interface WriteFuture

getException

public Throwable getException()

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

Specified by:

getException in interface WriteFuture

setWritten

public void setWritten()

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:

setWritten in interface WriteFuture

setException

public void setException(Throwable exception)

Sets the cause of the write 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 WriteFuture

await

public WriteFuture await()
                  throws InterruptedException

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 WriteFuture

Overrides:

await in class DefaultIoFuture

Returns:

the created WriteFuture

Throws:

InterruptedException

awaitUninterruptibly

public WriteFuture awaitUninterruptibly()

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 WriteFuture

Overrides:

awaitUninterruptibly in class DefaultIoFuture

Returns:

the current IoFuture

addListener

public WriteFuture addListener(IoFutureListener<?> listener)

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 WriteFuture

Overrides:

addListener in class DefaultIoFuture

removeListener

public WriteFuture removeListener(IoFutureListener<?> listener)

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 WriteFuture

Overrides:

removeListener in class DefaultIoFuture
