 EventExecutor executor)

Creates a new instance.

DefaultChannelGroupFuture

DefaultChannelGroupFuture(ChannelGroup group,
 java.util.Map<Channel, ChannelFuture> futures,
 EventExecutor executor)

Method Details

group

public ChannelGroup group()

Description copied from interface: ChannelGroupFuture

Returns the ChannelGroup which is associated with this future.

Specified by:

group in interface ChannelGroupFuture

find

public ChannelFuture find(Channel channel)

Description copied from interface: ChannelGroupFuture

Returns the ChannelFuture of the individual I/O operation which is associated with the specified Channel.

the matching ChannelFuture if found. null otherwise.

iterator

public java.util.Iterator<ChannelFuture> iterator()

Description copied from interface: ChannelGroupFuture

Returns the Iterator that enumerates all ChannelFutures which are associated with this future. Please note that the returned Iterator is unmodifiable, which means a ChannelFuture cannot be removed from this future.

Specified by:

iterator in interface ChannelGroupFuture

Specified by:

iterator in interface java.lang.Iterable<ChannelFuture>

isPartialSuccess

public boolean isPartialSuccess()

Description copied from interface: ChannelGroupFuture

Returns true if and only if the I/O operations associated with this future were partially successful with some failure.

Specified by:

isPartialSuccess in interface ChannelGroupFuture

public boolean isPartialFailure()

Description copied from interface: ChannelGroupFuture

Returns true if and only if the I/O operations associated with this future have failed partially with some success.

Specified by:

isPartialFailure in interface ChannelGroupFuture

addListener

public DefaultChannelGroupFuture addListener(GenericFutureListener<? extends Future<? super java.lang.Void>> listener)

Specified by:

addListener in interface Promise<java.lang.Void>

Overrides:

addListener in class DefaultPromise<java.lang.Void>

addListeners

public DefaultChannelGroupFuture addListeners(GenericFutureListener<? extends Future<? super java.lang.Void>>... listeners)
