You need to register resource factory.
You can use call
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put
to register resource factory.
And this is sample codes for xmi format file which is using
XMIResource interface.
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put
("*", <--- your file extension
new XMIResourceFactoryImpl() <--- the class to resource factory
{
public Resource createResource(URI uri)
{
XMIResource xmiResource = new XMIResourceImpl(uri);
return xmiResource;
}
});
You can provide your own resource factory class and resource class to
handle
your own file (if it is not xmi or xml file).
For more infomation, please refer to EMF users guide, session 3.4.2 and
3.4.3.
Regards,
Shu
