Package marauroa.server.game.db

Class DAORegister

java.lang.Object

marauroa.server.game.db.DAORegister

public class DAORegister
extends Object

Keeps track of the DAOs (data access objects) to use. They are registered using their class name:
register(CharacterDAO.class, new CharacterDAO());

Games can add their own DAOs. They can even replace framework DAOs with their own subclasses. Stendhal for example enhances the normal CharacterDAO with its own subclass to update a redundant table used by the Stendhal website:
DAORegister.get().register(CharacterDAO.class, new StendhalCharacterDAO());

Game should register their DAOs in the "initialize()" method of their DatabaseFactory, as defined in the server.ini:
database_implementation=games.demo.server.DemoDatabaseFactory
