Load Domain Model (File) into Diagram [message #756895]

Hi!

I want to load business objects (EMF format) into a new Graphiti diagram.

The thread "Create Diagram Model Programatically" has been of great help so far.

But my question is:
How do I get the business objects out of the domain model file?

My first naive attempt was:

ResourceSet resourceSet = new ResourceSetImpl();
Resource resource = resourceSet.getResource(domainModelFileURI, true);
try {
	resource.load(Collections.EMPTY_MAP);
} catch (IOException e) {
	e.printStackTrace();
}

All I get is resource = 'null'.

Thanks,
Matt

Hi Matt,

maybe the uri is wrong? If the resource is not null you can
retrieve its contents via getContents().
You may have a look at the TutorialUtil for inspiration.
Also, you may want to ponder on reusing the resource set of the diagram editor...
For pure EMF questions, please use the EMF forum.

Best, Tim

Hi Tim,

thanks for the quick reply!
Good to know my code is basically correct.
I will check the URI again.
( update: URI is correct. resource.getcontents() is not null, but empty. I will use the EMF Forum for details )

Sorry, I don't understand what you mean by "reusing the resource set of the diagram editor". Could you explain this?

best regards,
Matt

Hi Matt,

the diagram editor has a resource set where the resource
for the graphiti model is managed.
You might use this resource set instead of creating a new one.
You might have a look at the method saveToModelFile
in the TutorialUtil.

Best, Tim

Hi Tim,
thanks for your help.

I finally solved the problem.
If anybody has the same problem, here is my solution:

	
// LOAD OTX MODEL FROM FILE
ResourceSet resourceSet = new ResourceSetImpl();
URI fileURI = URI.createFileURI(new File("filepath.xml").getAbsolutePath() );
Resource poResource = resourceSet.getResource(fileURI, true);
		
// Add business objects to list
Set<EObject> eObjects = new HashSet<EObject>();
eObjects.addAll(poResource.getContents());
