Method Details

parent

ServerSocketChannel parent()

Description copied from interface: Channel

Returns the parent of this channel.

Specified by:

parent in interface Channel

Returns:

the parent channel. null if this channel does not have a parent channel.

config

SocketChannelConfig config()

Description copied from interface: Channel

Returns the configuration of this channel.

Specified by:

config in interface Channel

localAddress

java.net.InetSocketAddress localAddress()

Description copied from interface: Channel

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.

Specified by:

localAddress in interface Channel

Returns:

the local address of this channel. null if this channel is not bound.

remoteAddress

java.net.InetSocketAddress remoteAddress()

Description copied from interface: Channel

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.

Specified by:

remoteAddress in interface Channel

Returns:

the remote address of this channel. null 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 DefaultAddressedEnvelope.recipient() to determine the origination of the received message as this method will return null.
