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 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.

Protected constructors
ServerSocketFactory
protected ServerSocketFactory ()
Creates a server socket factory.
Public methods
createServerSocket
public abstract ServerSocket createServerSocket (int port)
Returns a server socket bound to the specified port. The socket is configured with the socket options (such as accept timeout) given to this 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.
| Parameters | |
|---|---|
| port | int: the port to listen to | 
| Returns | |
|---|---|
| ServerSocket | the ServerSocket | 
| Throws | |
|---|---|
| IOException | for networking errors | 
| SecurityException | if a security manager exists and its checkListenmethod doesn't allow the operation. | 
| IllegalArgumentException | if the port parameter is outside the specified range of valid port values, which is between 0 and 65535, inclusive. | 
createServerSocket
public ServerSocket createServerSocket ()
Returns an unbound server socket. The socket is configured with the socket options (such as accept timeout) given to this factory.
| Returns | |
|---|---|
| ServerSocket | the unbound socket | 
| Throws | |
|---|---|
| IOException | if the socket cannot be created | 
createServerSocket
public 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.
 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.
 
 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.
| Parameters | |
|---|---|
| port | int: the port to listen to | 
| backlog | int: how many connections are queued | 
| ifAddress | InetAddress: the network interface address to use | 
| Returns | |
|---|---|
| ServerSocket | the ServerSocket | 
| Throws | |
|---|---|
| IOException | for networking errors | 
| SecurityException | if a security manager exists and its checkListenmethod doesn't allow the operation. | 
| IllegalArgumentException | if the port parameter is outside the specified range of valid port values, which is between 0 and 65535, inclusive. | 
createServerSocket
public abstract ServerSocket createServerSocket (int port, int backlog)
Returns a server socket bound to 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.
 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.
 
 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.
| Parameters | |
|---|---|
| port | int: the port to listen to | 
| backlog | int: how many connections are queued | 
| Returns | |
|---|---|
| ServerSocket | the ServerSocket | 
| Throws | |
|---|---|
| IOException | for networking errors | 
| SecurityException | if a security manager exists and its checkListenmethod doesn't allow the operation. | 
| IllegalArgumentException | if the port parameter is outside the specified range of valid port values, which is between 0 and 65535, inclusive. | 
getDefault
public static ServerSocketFactory getDefault ()
Returns a copy of the environment's default socket factory.
| Returns | |
|---|---|
| ServerSocketFactory | the ServerSocketFactory |
