Class DefaultResourceSetFactory

java.lang.Object

org.gecko.emf.osgi.DefaultResourceSetFactory

All Implemented Interfaces:

ResourceSetFactory

public class DefaultResourceSetFactory
extends java.lang.Object
implements ResourceSetFactory

Implementation of a ResourceSetFactory. It hold the EPackage registry as well as the Factory registry. EPackage are dynamically injected as EPackageProvider instance. Factory instance are injected dynamically as ServiceReference instance. So they can be registered using their properties for contentTyp or fileExtension. Third additional ResourceSetConfigurator instance can be injected to customize the ResourceSet for further extension like custom serialization.
