Class BackendJokeSetOnly

  standup.joke.Backend
      standup.joke.BackendJokeSetOnly

All Implemented Interfaces:

Profileable

public class BackendJokeSetOnly
extends Backend

A subclass of Backend that "generates" jokes purely by retrieving pre-generated jokes found in the 'joke cache'.

This is used by the 'demo' version of STANDUP. It does not attempt to establish a connection to the SQL server, and can thus be run on machines where there is no access to PostgreSQL.

The joke cache is contained in a file in the /standup/resources/xml/ subdirectory found within the STANDUP .jar file.
