SocketImpl

SocketImpl

java.net

---

Java 1.0

This abstract class defines the methods necessary to implement communication through sockets. Different subclasses of this class may provide different implementations suitable in different environments (such as behind firewalls). These socket implementations are used by the Socket and ServerSocket classes. Normal applications never need to use or subclass this class.
