final override def localAddress: Option[SocketAddress]

Returns the local address where this channel is bound to. The returned SocketAddress is supposed to be down-cast into more concrete type such as InetSocketAddress to retrieve the detailed information.

final override def remoteAddress: Option[SocketAddress]

Returns the remote address where this channel is connected to. The returned SocketAddress is supposed to be down-cast into more concrete type such as InetSocketAddress to retrieve the detailed information.

Returns the remote address where this channel is connected to. The returned SocketAddress is supposed to be down-cast into more concrete type such as InetSocketAddress to retrieve the detailed information.

Attributes

Returns

the remote address of this channel. None if this channel is not connected. If this channel is not connected but it can receive messages from arbitrary remote addresses (e.g. DatagramChannel, use DatagramPacket#recipient() to determine the origination of the received message as this method will return None.

def shutdown(direction: ChannelShutdownDirection, future: ChannelFuture): ChannelFuture

Request shutdown one direction of the Channel and notify the ChannelFuture once the operation completes, either because the operation was successful or because of an error. When completed, the channel will either not produce any inbound data anymore, or it will not be possible to write data anymore, depending on the given ChannelShutdownDirection. Depending on the transport implementation shutting down the ChannelShutdownDirection.Outbound or ChannelShutdownDirection.Inbound might also result in data transferred over the network. Like for example in case of TCP shutting down the ChannelShutdownDirection.Outbound will result in a FIN that is transmitted to the remote peer that will as a result shutdown ChannelShutdownDirection.Inbound. This will result in having the ChannelShutdownDirection). method called of the next ChannelHandler contained in the ChannelPipeline of the Channel.
