Hi!
I want to create a dummy resource for each DSL-file which is loaded, i.e. dependent on the URI of the file. This shall be independent of the viewer I use (the generated XText editor or some ecore (reflective) viewer). By debugging I found out, that the common entry point for each viewer (to create resources) is
XTextResourceFactory.createResource(URI uri)
So I overwrote it and bounded it:
public Resource createResource(URI uri) {
Resource resource = super.createResource(uri);
// creating a dummy resource for dummy eObjects
dummyURI = uri.appendSegment(DUMMY_SEGMENT);
dummyResource = super.createResource(dummyURI); // not null
System.out.println("resource.getResourceSet() = " + resource.getResourceSet()); // resource set is null
// dummyResource = resource.getResourceSet().createResource(dummyURI);
return resource;
}
final String DUMMY_SEGMENT = "dummy";
URI dummyURI;
Resource dummyResource;
public URI getDummyURI() {
return dummyURI;
}
public Resource getDummyResource() {
return dummyResource;
}
I want to create some dummy EObject in my LinkingService and put it in that dummy resource. So I inject the IResourceFactory and my getLinkedObjects method looks like
...
EObject dummyObject = ...
if(resourceFactory instanceof MyDslXtextResourceFactory) {
Resource dummyResource = ((MyDslXtextResourceFactory) resourceFactory).getDummyResource();
System.out.println("dummyResource = " + dummyResource); // is null ???
dummyResource.getContents().add(dummyObject); // NullPointerException
return Collections.singletonList(dummyObject);
}
Does somebody know why the dummyResource gets null in the LinkingService?
And is there possibly a better place to add dynamically resources dependent on the URI of the file?
Best regards,
Alex.
