accessing runtime models with reflection [message #1837041]

Hi all, I have a doubt for which I couldn't find a solution. I have an EOL script that I launch programmatically with java standalone code. I set up the runtime config with java code in which I load models dynamically... I load all the models in a specific project folder. Now I have to access to these models in the eol script, but I only know how to use the models as variables... so If i have model1...modelk I can use them as variables but I think it would be nice to use reflection so I can access to these models with the string name.
Hope I have been clear.thanks

Hi Ludovico,

The following should do the trick.

for (m in System.context.modelRepository.models) {
  m.println();
  m.getAllOfType("Task").println();
}

Thanks,
Dimitris

Another quick question related to the same category. If the eol is executed programmatically the eol program does not resolve the external references I guess. In fact if I execute the same program with runtime config it returns the external refs. I can't find the property to be set programmatically when the model is loaded. I guessed it was EXPAND to be set to true but the result does not change...is there a way to resolve it from the java launcher ? Otherswise I guess I should use ecoreutil to resolve the proxy from eol...what do you guys suggest?

thanks a lot

The expand property should do the trick indeed; this is the property that the Eclipse-based development tools also use (see line 208 of EmfModelConfigurationDialog).

One reason why resolution may fail is if cross-references make use of platform:/ URLs, which are meaningless outside Eclipse/OSGi. Could this be the case? If not, please share a minimal example and I will investigate further.

Thanks,
Dimitris

I think you're right... i see the platform:/ url . I'll pack an example. Thanks

I created a minimal example with a standalone launcher ...the problem I still have is related to proxyuri that it is returned in standalone launcher but not using the runtimeconfig. Launching the eol from the runtime config I get the external reference resolved and printed correctly. On the other side I receive the proxyuri and i can't resolve it. The EXPAND prop is set to true...

thanks a lot for your help.

Hi Ludovico,

Replacing "model/qualitydef.model" in your Evaluation class with the following seems to be doing the trick.

 
URI.createFileURI(new File("model/qualitydef.model").getAbsolutePath()).toString()

Thanks,
Dimitris
