abstract public class: SocketFactory [javadoc | source]
java.lang.Object
   javax.net.SocketFactory

Direct Known Subclasses:
    VanillaSocketFactory, DefaultSSLSocketFactory, DefaultSocketFactory, SSLSocketFactory

This class creates sockets. It may be subclassed by other factories, which create particular subclasses of sockets and thus provide a general framework for the addition of public socket-level functionality.

Socket factories are a simple way to capture a variety of policies related to the sockets being constructed, producing such sockets in a way which does not require special configuration of the code which asks for the sockets:

Factory classes are specified by environment-specific configuration mechanisms. For example, the getDefault method could return a factory that was appropriate for a particular user or applet, and a framework could use a factory customized to its own purposes.

Constructor:
 protected SocketFactory()

Method from javax.net.SocketFactory Detail:
 public Socket createSocket() throws IOException 
    Creates an unconnected socket.
 abstract public Socket createSocket(String host,
    int port) throws IOException, UnknownHostException
    Creates a socket and connects it to the specified remote host at the specified remote port. This socket is configured using the socket options established for this factory.

    If there is a security manager, its checkConnect method is called with the host address and port as its arguments. This could result in a SecurityException.

 abstract public Socket createSocket(InetAddress host,
    int port) throws IOException
    Creates a socket and connects it to the specified port number at the specified address. This socket is configured using the socket options established for this factory.

    If there is a security manager, its checkConnect method is called with the host address and port as its arguments. This could result in a SecurityException.

 abstract public Socket createSocket(String host,
    int port,
    InetAddress localHost,
    int localPort) throws IOException, UnknownHostException
    Creates a socket and connects it to the specified remote host on the specified remote port. The socket will also be bound to the local address and port supplied. This socket is configured using the socket options established for this factory.

    If there is a security manager, its checkConnect method is called with the host address and port as its arguments. This could result in a SecurityException.

 abstract public Socket createSocket(InetAddress address,
    int port,
    InetAddress localAddress,
    int localPort) throws IOException
    Creates a socket and connect it to the specified remote address on the specified remote port. The socket will also be bound to the local address and port suplied. The socket is configured using the socket options established for this factory.

    If there is a security manager, its checkConnect method is called with the host address and port as its arguments. This could result in a SecurityException.

 public static SocketFactory getDefault() 
    Returns a copy of the environment's default socket factory.
