Class DbLoaderFactory<T extends Loader>

java.lang.Object
  blackboard.persist.DbLoaderFactory<T>

public class DbLoaderFactory<T extends Loader>
extends java.lang.Object

Helper factory class for implementing the "default" objects in loaders. This requires less code to be written in the loader interface. Now, to create the "default" factory, you do this: public static final DbPersisterFactory Default = DbPersisterFactory.newInstance(FooDbLoader.class); Though it is not an actual class in the loader interface, the client code will interact with it in the same way all current code does.
