channel - the Channel associated with this future

Method Detail

addListener

public void addListener(ChannelFutureListener listener)

Description copied from interface: ChannelFuture

Adds the specified listener to this future. The specified listener is notified when this future is done. If this future is already completed, the specified listener is notified immediately.

Specified by:

addListener in interface ChannelFuture

removeListener

public void removeListener(ChannelFutureListener listener)

Description copied from interface: ChannelFuture

Removes the specified listener from this future. The specified listener is no longer notified when this future is done. If the specified listener is not associated with this future, this method does nothing and returns silently.

Specified by:

removeListener in interface ChannelFuture

await
