public abstract class Factory

extends java.lang.Object

base class for all protocol factories

In the configuration there is a protocol assigned to each server. That means the class of the protocol factory is specified. For each new server object the factory's create() function is invoked to create a new protocol object. The server keeps that protocol object and manages the sockets and input/output streams for that protocol object. Depending on the return value the socket is kept alive or closed. If an Exception is caught, the server and the protocol object are discarded. The mechanism behind (ThreadManager) creates server objects on demand.
