Interface SocketFactory

All Known Implementing Classes:

DefaultSocketFactory

public interface SocketFactory

The SocketFactory interface provides a means for the programmer to control the creation of sockets and provide his own Socket implementations for use by all classes derived from SocketClient . This allows you to provide your own Socket implementations and to perform security checks or browser capability requests before creating a Socket.

createServerSocket

public java.net.ServerSocket createServerSocket(int port)
                                         throws java.io.IOException

Creates a ServerSocket bound to a specified port. A port of 0 will create the ServerSocket on a system-determined free port.

Parameters:

port - The port on which to listen, or 0 to use any free port.

Returns:

A ServerSocket that will listen on a specified port.

Throws:

java.io.IOException - If an I/O error occurs while creating the ServerSocket.

createServerSocket
