Constructor Detail

DefaultChannelGroup

public DefaultChannelGroup()

Creates a new group with a generated name.

DefaultChannelGroup

public DefaultChannelGroup(java.lang.String name)

Creates a new group with the specified name. Please note that different groups can have the same name, which means no duplicate check is done against group names.

Method Detail

Overrides:

toArray in class java.util.AbstractCollection<Channel>

close

public ChannelGroupFuture close()

Description copied from interface: ChannelGroup

Closes all Channels in this group. If the Channel is connected to a remote peer or bound to a local address, it is automatically disconnected and unbound.

Specified by:

close in interface ChannelGroup

Returns:

the ChannelGroupFuture instance that notifies when the operation is done for all channels

disconnect

public ChannelGroupFuture disconnect()

Description copied from interface: ChannelGroup

Disconnects all Channels in this group from their remote peers.

Specified by:

disconnect in interface ChannelGroup

Returns:

the ChannelGroupFuture instance that notifies when the operation is done for all channels

setInterestOps

public ChannelGroupFuture setInterestOps(int interestOps)

Description copied from interface: ChannelGroup

Calls Channel.setInterestOps(int) for all Channels in this group with the specified interestOps. Please note that this operation is asynchronous as Channel.setInterestOps(int) is.

Specified by:

setInterestOps in interface ChannelGroup

Returns:

the ChannelGroupFuture instance that notifies when the operation is done for all channels

setReadable

public ChannelGroupFuture setReadable(boolean readable)

Description copied from interface: ChannelGroup

Specified by:

setReadable in interface ChannelGroup

Returns:

the ChannelGroupFuture instance that notifies when the operation is done for all channels

unbind

public ChannelGroupFuture unbind()

Description copied from interface: ChannelGroup

Unbinds all Channels in this group from their local address.

Specified by:

unbind in interface ChannelGroup

Returns:

the ChannelGroupFuture instance that notifies when the operation is done for all channels

write

public ChannelGroupFuture write(java.lang.Object message)

Description copied from interface: ChannelGroup

Writes the specified message to all Channels in this group. If the specified message is an instance of ChannelBuffer, it is automatically duplicated to avoid a race condition. Please note that this operation is asynchronous as Channel.write(Object) is.

Specified by:

write in interface ChannelGroup

Returns:

the ChannelGroupFuture instance that notifies when the operation is done for all channels

write

public ChannelGroupFuture write(java.lang.Object message,
                                java.net.SocketAddress remoteAddress)

Description copied from interface: ChannelGroup

Writes the specified message with the specified remoteAddress to all Channels in this group. If the specified message is an instance of ChannelBuffer, it is automatically duplicated to avoid a race condition. Please note that this operation is asynchronous as Channel.write(Object, SocketAddress) is.

Specified by:

write in interface ChannelGroup

Returns:

the ChannelGroupFuture instance that notifies when the operation is done for all channels
