remoteAddress
public java.net.InetSocketAddress remoteAddress()
Description copied from interface:Channel
Returns the remote address where this channel is connected to. The returnedSocketAddress
is supposed to be down-cast into more concrete type such asInetSocketAddress
to retrieve the detailed information.- Specified by:
