[henshin-dev] Programmatically executing out-place transformations

[Vlad Acretoaie <rvac@xxxxxx>]

Hi,

 

I would like to invoke a Henshin transformation programmatically and save the target model in a different file than the source model (i.e. I would like my transformation to be out-place). So far I was able to do this as follows, using the “ePackage” output parameter  of my transformation:

 

UnitApplication application = new UnitApplicationImpl(engine, graph, unit, null);

application.execute(null);

EPackage result = (EPackage) application.getResultParameterValue("ePackage");

resourceSet.saveEObject(result, "target.ecore");

 

So my question is: Is there a way of executing an out-place transformation without depending on the existence of an appropriate output parameter of the transformation? I would like to simply save the entire target model, regardless if the transformation has any parameters or not. I suspect this is possible, since the Henshin Eclipse plug-in is able to do it when executing transformations using the GUI.

 

Cheers,

Vlad
