Class DefaultSocketFactory

Implemented Interfaces:
SocketFactory

public class DefaultSocketFactory
extends java.lang.Object
implements SocketFactory

DefaultSocketFactory implements the SocketFactory interface by simply wrapping the java.net.Socket and java.net.ServerSocket constructors. It is the default SocketFactory used by SocketClient implementations.

Method Details

createServerSocket

public ServerSocket createServerSocket(int port)
            throws IOException
Creates a ServerSocket bound to a specified port. A port of 0 will create the ServerSocket on a system-determined free port.

Specified by:
createServerSocket in interface SocketFactory
Parameters:
port - The port on which to listen, or 0 to use any free port.
Returns:
A ServerSocket that will listen on a specified port.

createServerSocket

public ServerSocket createServerSocket(int port,
                                       int backlog)
            throws IOException
Creates a ServerSocket bound to a specified port with a given maximum queue length for incoming connections. A port of 0 will create the ServerSocket on a system-determined free port.

Specified by:
createServerSocket in interface SocketFactory
Parameters:
port - The port on which to listen, or 0 to use any free port.
backlog - The maximum length of the queue for incoming connections.
Returns:
A ServerSocket that will listen on a specified port.

createServerSocket

public ServerSocket createServerSocket(int port,
                                       int backlog,
                                       InetAddress bindAddr)
            throws IOException
Creates a ServerSocket bound to a specified port on a given local address with a given maximum queue length for incoming connections. A port of 0 will create the ServerSocket on a system-determined free port.

Specified by:
createServerSocket in interface SocketFactory
Parameters:
port - The port on which to listen, or 0 to use any free port.
backlog - The maximum length of the queue for incoming connections.
bindAddr - The local address to which the ServerSocket should bind.
Returns:
A ServerSocket that will listen on a specified port.

Specified by:
createSocket in interface SocketFactory
Parameters:
address - The address of the host to connect to.
port - The port to connect to.
Returns:
A Socket connected to the given host and port.
