[Xpand] Can Xpand process two input models together? [message #521438]

Hi everyone,

I currently have a Xpand template to generate code for one model, and it works.

However, I want to have another input model (different domain) to generate something else in the same file (aspect-oriented might not work well at this point), therefore, I have another import statement:

import Metamodel1;
import Metamodel2;
...

However, I do not know how to access and trigger the elements in the 2nd metamodel. For example:

<<DEFINE d1 FOR Metamodel1::Element1>>
void function1()
{
somestatement;
somestatement;

<<EXPAND d2 FOR ???>> // The problem is I do not know how to put the target here. How can I access the second model?

}
<<ENDDEFINE>>

<<DEFINE d2 FOR Metamodel2::Element1>>
... ...
<<ENDDEFINE>>

Any idea? Is it doable?

Also, a related question is: is there any statement in Xpand or Xpand extension that can get all instances of a certain type of elements directly without using a container?

Thanks a lot.

Yu

To get all instances of a certain type, you have to use Xtend

Look at the last messages.

One day I shall master M2T, but that day has yet to come...

another possibility is to pass both to your define

«DEFINE definionName(OtherType otherType) FOR Type»
«ENDDEFINE»

then you can access the second model using the variable otherType
