Interface SocketFactory

All Known Implementing Classes:
  DefaultSocketFactory

    public interface SocketFactory

Factory to create various types of sockets. For socket creation, a service name can be passed as argument: an implementation could look up a service description (e.g. port) and create the socket, ignoring the passed port and possibly also the bind address.

Ephemeral ports can be created by passing 0 as port, or (if the port is ignored), an implementation could pass in a special service name (e.g. "EPHEMERAL"), this is implementation dependent.

The socket creation methods have the same parameter lists as the socket constructors, e.g. `createServerSocket(String, int, int)` is the same as `java.net.ServerSocket(int,int)`.
