Examples of java.net.SocketImpl

java.net.SocketImpl
The abstract class SocketImpl is a common superclass of all classes that actually implement sockets. It is used to create both client and server sockets.
A "plain" socket implements these methods exactly as described, without attempting to go through a firewall or proxy. @author unascribed @version 1.45, 03/08/07 @since JDK1.0
