Method Detail

getDefault

public static ServerSocketFactory getDefault()

Gets the default server socket factory of the system which can be used to create new server sockets without creating a subclass of this factory.

Returns:

the system default server socket factory.

createServerSocket

public ServerSocket createServerSocket()
                                throws IOException

Creates a new server socket which is not bound to any local address. This method has to be overridden by a subclass otherwise a SocketException is thrown.

Returns:

the created unbound server socket.

Throws:

IOException - if an error occurs while creating a new server socket.

createServerSocket

public abstract ServerSocket createServerSocket(int port)
                                         throws IOException

Creates a new server socket which is bound to the given port with a maximum backlog of 50 unaccepted connections.

Parameters:

port - the port on which the created socket has to listen.

Returns:

the created bound server socket.

Throws:

IOException - if an error occurs while creating a new server socket.

createServerSocket

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

Creates a new server socket which is bound to the given port and configures its maximum of queued connections.

Parameters:

port - the port on which the created socket has to listen.

backlog - the maximum number of unaccepted connections. Passing 0 or a negative value yields the default backlog of 50.

Returns:

the created bound server socket.

Throws:

IOException - if an error occurs while creating a new server socket.

createServerSocket

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

Creates a new server socket which is bound to the given address on the specified port and configures its maximum of queued connections.

Parameters:

port - the port on which the created socket has to listen.

backlog - the maximum number of unaccepted connections. Passing 0 or a negative value yields the default backlog of 50.

iAddress - the address of the network interface which is used by the created socket.

Returns:

the created bound server socket.

Throws:

IOException - if an error occurs while creating a new server socket.
