Class SocketFactory

public abstract class SocketFactory extends Object

A factory for client sockets. The purpose of this class is to serve as the superclass of server socket factories that produce client sockets of a particular type, such as Secure Socket Layer (SSL) sockets.

Constructor Summary
protected	SocketFactory() Default 0-arguments constructor.

Method Summary
Socket	createSocket() Returns an unbound client socket.
abstract Socket	createSocket(String host, int port) Creates a socket connected to a given host on a given port.
abstract Socket	createSocket(String host, int port, InetAddress localHost, int localPort) Creates a socket connected to a given host on a given port, connecting locally to the interface with the given address and port.
abstract Socket	createSocket(InetAddress host, int port) Creates a socket connected to a given host on a given port.
abstract Socket	createSocket(InetAddress hast, int port, InetAddress localHost, int localPort) Creates a socket connected to a given host on a given port, connecting locally to the interface with the given address and port.
static SocketFactory	getDefault() Returns the default socket factory.
