public abstract class ServerSocketFactory extends Object
Like socket factories, server Socket factory instances have methods used to create sockets. There is also an environment specific default server socket factory; frameworks will often use their own customized factory.
SocketFactory| Modifier | Constructor and Description | 
|---|---|
| protected  | ServerSocketFactory()Creates a server socket factory. | 
| Modifier and Type | Method and Description | 
|---|---|
| ServerSocket | createServerSocket()Returns an unbound server socket. | 
| abstract ServerSocket | createServerSocket(int port)Returns a server socket bound to the specified port. | 
| abstract ServerSocket | createServerSocket(int port,
                  int backlog)Returns a server socket bound to the specified port, and uses the
 specified connection backlog. | 
| abstract ServerSocket | createServerSocket(int port,
                  int backlog,
                  InetAddress ifAddress)Returns a server socket bound to the specified port,
 with a specified listen backlog and local IP. | 
| static ServerSocketFactory | getDefault()Returns a copy of the environment's default socket factory. |

 If there is a security manager, its checkListen
 method is called with the port argument as its
 argument to ensure the operation is allowed. This could result
 in a SecurityException.

 The backlog argument must be a positive
 value greater than 0. If the value passed if equal or less
 than 0, then the default value will be assumed.

ServerSocket.ServerSocket(int, int)public abstract ServerSocket createServerSocket(int port, int backlog, InetAddress ifAddress) throws IOException
 The ifAddress argument can be used on a multi-homed
 host for a ServerSocket that will only accept connect
 requests to one of its addresses. If ifAddress is null,
 it will accept connections on all local addresses. The socket is
 configured with the socket options (such as accept timeout) given
 to this factory.
 
 The backlog argument must be a positive
 value greater than 0. If the value passed if equal or less
 than 0, then the default value will be assumed.
