The abstract class <code>SocketImpl</code> is a common superclass

of all classes that actually implement sockets. It is used to

create both client and server sockets.

抽象类SocketImpl是所有实际实现套接字的类的父类，既用于创建客户端，也用于创建服务器。

A "plain" socket implements these methods exactly as

described, without attempting to go through a firewall or proxy.

空白套接字实现了下面描述的方法，并不考虑通过防火墙或代理服务器。
