[Xcore] Create an instance using XYZFacttoy [message #800796]

when I define a model using XCore and provide implementations of operations there is a case where I would like to create a new EObject instance of one of my classes I defined in my model. however I cannot access the XYZPackage.eInstance to obtain the XYZFactory. What am I do wrong when using that approach?

Thanks
Markus

Markus,

You should be able to use XyzFactory::eINSTANCE.createAbc. Note that
the XcoreJvmInferrer is relatively incomplete so much of the knowledge
about the Java model that's generated won't be known until it's been
generated once so you'll need to save once in a while to refer to the
new things in the bodies.

Thank you Ed. That worked. I was unware that the syntax to access static members is "::". With some tweaking in the save cycle I managed afterwards. Markus

Hm, this doesn't work anymore with the xcore juno build.
The xcore editor only knows XYZFactory.INSTANCE so the generated code fails to compile.
(when changing to eINSTANCE no code is generated)

Sandro,

Did you change some of the GenModel options such as those to suppress
interfaces or those to suppress EMF metadata? I don't think the
XcoreJvmInferrer takes all possible options into account. When you say
the generated code fails to compile, you mean the part you've specified
with an Xbase access to the factory instance in the block expression of
some operation or derived feature?
