Hi,

The Java model you obtained (that conforms to the Java metamodel provided by MoDisco and defined in Ecore) can be loaded in memory as any EMF model.
You should check some EMF tutorials to see how to perform this programmatically.

As far as the structure of the produced Java model is concerned, you should take a look to the MoDisco documentation related to the Java metamodel and its available API.
Cf. the MoDisco Documentation -> MoDisco User Guide -> Technologies -> Java -> Java metamodel.
In you case, I guess you first need to access to the main MethodDeclaration from the corresponding ClassDeclaration.

Kind regards,

The Java model discoverer will return you a full Java model from your selected Java project.
You then have to navigate this model in order to get the specific method you want to study and/or transform further.
You can use the provided/generated Java API (corresponding to the Java metamodel) in order to realize such a navigation.

I have question when I install modisco as eclipse plugin Can you develop a desktop application to generate Java model .
i see in Java Discoverer API http://download.eclipse.org/modeling/mdt/modisco/nightly/doc/org.eclipse.modisco.doc/ that say must add the following plug-in dependencies to your project ( Require-Bundle in your Manifest.MF):

org.eclipse.gmt.modisco.java
org.eclipse.modisco.java.discoverer
org.eclipse.modisco.infra.discovery.core

or just develop plugin

and another question in :
javaDiscoverer.discoverElement(javaProject, monitor);
is the javaProject parameter is file path

The MoDisco components (including the Java model discoverer and corresponding Java metamodel) are implemented as plain Eclipse plugins.
As any plugins, they can be integrated in Eclipse RCP applications you can build.
However, we do not currently provide standalone versions of these MoDisco components.
