Parameter Initialization [message #1065076]

Hi all,

I am trying to create a new Java Discoverer. I created a Discoverer extending AbstractDiscoverJavaModelFromProject. I would like to initialize the parameter ELEMENTS_TO_ANALYZE. I create a static method with the annotation @ParameterInitialValue in order to initialize the value.

Unfortunately, this method is never called and the ELEMENTS_TO_ANALYZE parameter is always null.

public class MyJavaDiscoverer extends
AbstractDiscoverJavaModelFromProject<IProject> {

	@ParameterInitialValue(name = "ELEMENTS_TO_ANALYZE")
	public static ElementsToAnalyze getElementsToAnalyzeInitialValue(final IProject project) {
           ...
	}
}

Did I forget anything ?

Regards,
Florian

Hi,

This annotation is not written to be used when you launch a discoverer programmaticaly, this kind of annotations are used by the GUI to now which are the parameters that need to be asked to the end user of modisco.

If you want to launch your java discoverer on an IProject iproject you shoud do something like:

 youJavaDiscovererInstance.discoverElement(iproject, new NullProgressMonitor());

of course it should be done only after initializing all the other needed parameters using the correct setters.

I hope it will help you.

Best regards,

Guillaume

Hi,

In fact, I use my discoverer from the GUI. I declared an extension from the extension point org.eclipse.modisco.infra.discovery.ui.discoverer.

My discoverer is identical to the discoverer DiscoverJavaModelFromProject (org.eclipse.modisco.java.discoverer). The only difference between this discoverer and my discoverer is in the saveTargetModel() method where I transform the java model into my model before persisting it.

I need the initialization of the ELEMENTS_TO_ANALYZE parameter in order to display the JavaElementsToAnalyzeDialog for dependencies selection.

I tried to extends the DiscoverJavaModelFromProject but I encountered the same issue. It is very weird because I am able to add parameter with @Parameter.

Any idea ?

Regards
Florian

Hi,

Sorry, I wasn't understanding what you were wanting to do.

Maybe it's just a stupid question but what append if you override just the saveTargetModel method and just use the getElementsToAnalyzeInitialValue method from the inherited class (without overriding) ?

In fact I don't really know where this getElementsToAnalyzeInitialValue is called in the java discoverer, I have searched for it and did not find it...

So I think I'm out of ideas.

Regards,

Guillaume
