[QVTo] Register blackbox and "Strings" units on a standalone application [message #1490938]

Hello everybody,

I am using "TransformationExecutor" to execute my QVTo specification.

In my specification, I import a blackbox unit and "Strings" and they work well in a standard execution (i.e. using the standard interpreter).

However, these units are not recognized in my Java application and I get the following error message:

"Cannot find imported compilation unit 'Strings'" in the "Strings" case.

I suppose that I have to "register" these units in my code, but I do not know how I can do it.

Thanks,

CarlosG

I see there is a similar question on: https://www.eclipse.org/forums/index.php/t/458642/, but without answer...

Anyway, I found a solution for registering blackbox units using the QVTo version in developing (org.eclipse.qvto.git mater branch). It is detailed on: https://bugs.eclipse.org/bugs/show_bug.cgi?id=326871

In this version, TransformationExecutor class contains a BlackboxRegistry interface that is used to register a blackbox unit. Here, an example taken from https://bugs.eclipse.org/bugs/show_bug.cgi?id=326871:

TransformationExecutor.BlackboxRegistry.INSTANCE.registerModules(BlackboxLibrary.class);

Where "BlackboxLibrary" is the class that contains the blackbox operators. I attach a complete example.

I would like to know when will this functionality be available in nightly or stable version? Is there any other solution?

Thanks,

CarlosG

Hi

I think you'll find it in the M3 build.

PLease use the QVTo newsgroup/forum for QVTo messages.
