public class DefaultChannelProgressivePromise
extends DefaultProgressivePromise<java.lang.Void>
implements ChannelProgressivePromise

The default ChannelProgressivePromise implementation. It is recommended to use Channel.newProgressivePromise() to create a new ChannelProgressivePromise rather than calling the constructor explicitly.

Constructor Detail

DefaultChannelProgressivePromise

public DefaultChannelProgressivePromise(Channel channel)

Creates a new instance.

Parameters:

channel - the Channel associated with this future

DefaultChannelProgressivePromise

public DefaultChannelProgressivePromise(Channel channel,
                                        EventExecutor executor)

Creates a new instance.

Parameters:

channel - the Channel associated with this future

Method Detail

executor

protected EventExecutor executor()

Description copied from class: DefaultPromise

Get the executor used to notify listeners when this promise is complete.

It is assumed this executor will protect against StackOverflowError exceptions. The executor may be used to avoid StackOverflowError by executing a Runnable if the stack depth exceeds a threshold.

Overrides:

executor in class DefaultPromise<java.lang.Void>

Returns:

The executor used to notify listeners when this promise is complete.

channel

public Channel channel()

Description copied from interface: ChannelFuture

Returns a channel where the I/O operation associated with this future takes place.
