| accessing a genmodel programmatically [message #643685] |

Hi
I'm loading an EPackage programmatically specifying the ecore file,
e.g., "mypatch/to/my.ecore". Now, I'd like to access the corresponding
genmodel file.
Is there a direct way to achieve this? Let's say that I know that the
genmodel is always in the same directory of the ecore file, but how can
I retrieve such information once I have the EPackage (suppose I don't
have the information about the ecore package anymore)?
Besides that, can I simply load the genmodel as a standard resource or
should I use a specific method?
many thanks in advance
Lorenzo

From EcorePlugin:

URI} (represented as a String)
* to the location of the GenModel containing a GenPackage for the
package (represented as a {@link URI URI}).

Assuming it's registered, all you need to know is the nsURI of the package.

The right resource factory should be registered to load it normally.
Look closely at what the GenModelEditor does if you really want to use
it to generate something...

Hi Ed
I tried with the following snippet (where model contains an instance of
EPackage):
EPackage ePackage = model.getEPackage();
EPackage.Registry.INSTANCE.put(ePackage.getNsURI(), ePackage);
Map<String, URI> ePackageNsURIToGenModelLocationMap =
EcorePlugin.getEPackageNsURIToGenModelLocationMap();
URI uri = ePackageNsURIToGenModelLocationMap.get(ePackage.getNsURI());
System.out.println(uri);
but it does not work: the map is an empty map... am I missing something?
thanks in advance
Lorenzo

Th looks like a bad idea. If the model is registered, the package
should already be in the global registry.

Are you running stand alone or in an Eclipse environment? Plugin
registration only works when running under Equinox.

I'm trying this code in a junit test (not a plugin junit test), so this
won't work will it?
thanks

Lorenzo,
No, it won't work without the plugin.xml extension point processing.
Best to use a plugin JUnit test.

Hi Ed
then I probably have to find another way since I'd like to use this code
also in a standalone application (not running in eclipse). There's no
way to use the below code in a standalone application, is there?
thanks

Lorenzo,
Well, if I were made of time, I'd look into integrating the patches in
https://bugs.eclipse.org/bugs/show_bug.cgi?id=271253 I wonder though
if it's really entirely impossible to run your application as an Equinox
application?

I'd like to be able to run it both as an Equinox application and as a
standalone command line application...
