I would like to generate a variable with an initial value or alternative a static or non static initializer to initialize the variable.
How can I do this with present Xbase means?

on which level? within a method? partial inference of bodies is still not possible afaik,
as a field?

members += entity.toField("entityName", it.newTypeRef("String")) [
				initializer = '''"«entity.name»"'''
			]

I have a specific usecase for such a desire. Let's say I have a specialized XBlockExpression and inside that XBlockExpression I want to have access to a local variable which has been created automatically.

MySpecialBlock {
   if (specialLocalVariable != null) {
   }
}

Is this possible? Maybe do this in the TypeComputer?

Another idea could be to generate a XVariable instance in the DerivedStateProcessor and attach it to the EObject of my special XBlockExpression so I can access and add that variable to the local scope in the TypeComputer later? Would that be a way forward and how do I correctly access the required JvmType in the DerivedStateProcessor?

Thank you for that hint. I think that was what I was looking for.
