Class XMLResourceImpl

java.lang.Object

ResourceImpl

org.eclipse.emf.ecore.xmi.impl.XMLResourceImpl

All Implemented Interfaces:

XMLResource

Direct Known Subclasses:

GenericXMLResourceImpl, XMIResourceImpl

public class XMLResourceImpl
extends ResourceImpl
implements XMLResource

This class implements the XMLResource interface. It overloads the doLoad method to invoke the XML deserializer rather than using the default XMI loader.
