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。
 <p>
 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。
