public abstract class TCPHandler

extends Handler

Abstract service for handling client connections.

This class processes the client requests. It works in tight cooperation with the TCPIPServer and TCPListener objects.

In order to develop a real handler the abstract handle(Socket) method must be overriden by the subclasses.
