Class ServerSocketFactory

    java.lang.Object
      |
      +--javax.net.ServerSocketFactory

Direct Known Subclasses:
  SSLServerSocketFactory

public abstract class ServerSocketFactory
extends Object

This class creates server sockets. It may be subclassed by other factories, which create particular types of server sockets. This provides a general framework for the addition of public socket-level functionality. It it is the server side analogue of a socket factory, and similarly provides a way to capture a variety of policies related to the sockets being constructed.

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.

Constructor Summary
`protected` | `ServerSocketFactory()` Constructor is used only by subclasses.

Method Summary
`abstract ServerSocket` | `createServerSocket(int port)` Returns a server socket which uses all network interfaces on the host, and is bound to the specified port.
`abstract ServerSocket` | `createServerSocket(int port, int backlog)` Returns a server socket which uses all network interfaces on the host, is bound to a the specified port, and uses the specified connection backlog.
`abstract ServerSocket` | `createServerSocket(int port, int backlog, InetAddress ifAddress)` Returns a server socket which uses only the specified network interface on the local host, is bound to a the specified port, and uses the specified connection backlog.
`static ServerSocketFactory` | `getDefault()` Returns a copy of the environment's default server socket factory.

Constructor Detail

### ServerSocketFactory

    protected ServerSocketFactory()

  Constructor is used only by subclasses.

Method Detail

### getDefault

    public static ServerSocketFactory getDefault()

  Returns a copy of the environment's default server socket factory.

### createServerSocket

    public abstract ServerSocket createServerSocket(int port)
                                             throws IOException

  Returns a server socket which uses all network interfaces on the host, and is bound to the specified port.
  Parameters:
    `port` - the port to listen to

### createServerSocket

    public abstract ServerSocket createServerSocket(int port,
                                                    int backlog)
                                             throws IOException

  Returns a server socket which uses all network interfaces on the host, is bound to a the specified port, and uses the specified connection backlog. The socket is configured with the socket options (such as accept timeout) given to this factory.
  Parameters:
    `port` - the port to listen to
    `backlog` - how many connections are queued

### createServerSocket

    public abstract ServerSocket createServerSocket(int port,
                                                    int backlog,
                                                    InetAddress ifAddress)
                                             throws IOException

  Returns a server socket which uses only the specified network interface on the local host, is bound to a the specified port, and uses the specified connection backlog. The socket is configured with the socket options (such as accept timeout) given to this factory.
  Parameters:
    `port` - the port to listen to
    `backlog` - how many connections are queued
    `ifAddress` - the network interface address to use
