* socket to a local {@link SocketAddress address}, the {@link #getLocalAddress()
* getLocalAddress} method returns the address that the socket is bound to, and
* the {@link #setOption(SocketOption,Object) setOption} and {@link

* <p> The {@link #bind bind} and {@link #setOption setOption} methods that do
* not otherwise have a value to return are specified to return the network
* channel upon which they are invoked. This allows method invocations to be
* chained. Implementations of this interface should specialize the return type
* so that method invocations on the implementation class can be chained.
