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.

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.

public abstract ServerSocket createServerSocket(int port) throws IOException
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.

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

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.
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.
