Interface ModelLoader

All Known Implementing Classes:
NextGenInvocation
public interface ModelLoader

A ModelLoader is responsible for creating an instane of Model from a given URI. It is called from the NextGen whenever a new instance of the model is needed. Typically every cartridge has at least one ModelLoader.

You should not buffer the model instances. This can lead to unpredictable side effects when transformations running on that model.

The ModelLoader is located via the java intern ServiceLoader-Mechanism. So it is possible that there are more than one model loader in a generation session.
