Getting applied profile names programmatically? [message #476813]

Hello all,

I've looked through many profile-related posts on the newsgroup here,
and haven't been able to put my finger on the source of my troubles.
I'm loading a UML2 model programmatically with the following code:

public static Model loadFromFile(String path) {
ResourceSet rs = new ResourceSetImpl();
rs.getResourceFactoryRegistry().getExtensionToFactoryMap().p ut(
"uml", new XMIResourceFactoryImpl());
URI uri = URI.createFileURI(path);
EClass eClass = UMLPackage.eINSTANCE.getModel();
Model m = (Model) EcoreUtil.getObjectByType(
rs.getResource(uri, true).getContents(), eClass);
return m;
}

I'm writing a UML simulator that will rely on information supplied in a profile,
and as a first step, I want to check that the profile is applied. I wrote the
following code to do so:

boolean foundProfile = false;
for (Profile p : m.getAllAppliedProfiles()) {
if ("hydra-uml".equals(p.getName())) {
foundProfile = true;
break;
}
}
if (!foundProfile)
throw new HydraException(...);

Running this code on a simple test model with some applied profiles fails, however.
getAppliedProfiles() returns Profile instances representing the applied profiles,
but getName() returns null, and using the debugger I can see that only the eProxyURI
attribute on the ProfileImpl instances is initialized.

What do I need to do to get access to the names of these profiles? This code is all
stand-alone, not running within an Eclipse workbench.

Thanks,
-Matt

I've continued reading profile-related posts here on the newsgroup, and think perhaps
I'm zeroing in on my problem. I'm using the Papyrus plugin to edit my profile and model.
Here's a snippet from the UML model file:

<profileApplication xmi:id="_frAlQLe8Edy1zMLaMA2OeQ">
<eAnnotations xmi:id="_frJvMLe8Edy1zMLaMA2OeQ" source="http://www.eclipse.org/uml2/2.0.0/UML">
<references xmi:type="ecore:EPackage" href=" ../resources/edu/msu/cse/sens/hydra/semantics/hydra-uml.prof ile.uml#_79Ygobe6Edy1zMLaMA2OeQ "/>
</eAnnotations>
<appliedProfile href=" ../resources/edu/msu/cse/sens/hydra/semantics/hydra-uml.prof ile.uml#_pi624Lb-Edy1zMLaMA2OeQ "/>
</profileApplication>

The URI is relative to the location of the model itself. How does EMF resolve such URIs?
Would EMF be able to find the profile using this URI when loading the model
programmatically in a stand-alone environment?

If this is in fact my problem, what are my options?

Thanks,
-Matt

Matt,

These URIs are resolved like any other cross document reference in EMF...
the proxies should be resolved succesfully, assuming the referenced resource
is located in the expected relative location. Note that when loading
models/profiles programatically, there are a few preparatory steps that must
be taken - see the articles on the documentation page and the FAQ for
details.
