Resolving Crossreferences in Eclipse context [message #985460]

I'd like to resolve crossreferences across multiple files in my DSL to display some actual values in Tooltips.

Multiple files are included with explicit include statements like in C. I have a class, that processes reads these include statements, put the referenced files in a ResourceSet and calls EcoreUtil.resolveAll() on the ResourceSet to resolve crossreferences across multiple files.

This works fine when running it Standalone after calling StandaloneSetup. When called in EObjectDocumentationProvider or anywhere else in the editor context crossreferences don't get resolved and remain as "Link<someNumbers>" in the Model.

Why does EcoreUtil.resolveAll() not work in the eclipse context and how can I resolve these crossreferences?

I'm sure, I'm doing something horribly wrong, but I haven't found the right way yet. Wink

It's a bit messy. Maybe I need to clean that up...

List<Resource> result = new ArrayList<Resource>();
URI rootFile = URI.createFileURI(filename);
Resource rootResource = null;
ResourceSet rs = new ResourceSetImpl();
rootResource = rs.getResource(rootFile, true);

<recursion that adds imported files to result>

result.add(0, rootResource);
ResourceSet resourceSet = new ResourceSetImpl();
for(Resource resource : result) {
	resourceSet.getResource(resource.getURI(), true);
}
EcoreUtil.resolveAll(resourceSet);

I hope that's all of the relevant lines.

I forgot... the List<Resource> is returned in a Variable resources and then this happens:

		List<Resource> resources = createResources(filename);
		if (resources != null) {
			ResourceSet resourceSet = new ResourceSetImpl();
			for(Resource resource : resources) {
				resourceSet.getResource(resource.getURI(), true);
			}
			EcoreUtil.resolveAll(resourceSet);

I really need to clean up this mess...

Use Iresourcesetprovider to get the resourceset

ok, I used


IResourceSetProvider resourceSetProvider;
ResourceSet resourceSet = resourceSetProvider.get(ResourcesPlugin.getWorkspace().getRoot().getProject());

to initialize the ResourceSet but the references still don't get resolved. Have I used IResourceSetProvider correctly?

Can you give more Context? How where do you call the stuff. Are you
sure you use the right project?

I got it...

Here's something for others that have this problem:
To get the resourceSet from a URI:

IResourceSet resourceSet = null;
if (resourceSetProvider != null) {
	IWorkspace workspace = ResourcesPlugin.getWorkspace();
	String s = uri.isPlatformResource() ? uri.toPlatformString(true) : uri.toString();
	IPath path = new Path(s);
	IResource resource = workspace.getRoot().getFile(path);
	IProject project = null == resource ? null : resource.getProject();
	resourceSet = resourceSetProvider.get(project==null?);
}else{
	resourceSet = new ResourceSetImpl();
}

The ResourceSetProvider can be initialized by Guice. By supplying (optional = true) it will be null when running standalone, thus explaining the if-clause above.

(optional = true)
IResourceSetProvider resourceSetProvider;

If this solution is stupid, please tell me...
