How to specify an array value in mwe2 [message #1772598]

So if my fragment class has a String array data member, or an ArrayList<String> data member, how do I initialize it in mwe2?

for example:

mwe2...
fragment = MyFragment {
	myList = ArrayList {
		// ?????
	}
}
...

fragment...
class MyFragment extends AbstractXtextGeneratorFragment {
	@Accessors ArrayList<String> myList
....
}

I can't seem to find the syntax for filling the ArrayList. Or the only way is to create addMyListItem(String i) method?

You usually add a method addXxxx
And the do xxxx = "a" xxxx="b" in the workflow

you might have a look at this hidden treasure that was removed for whyever from the main xtext doc (maybe cause it parially outdated, i dont know)

example:

validator = {
composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
composedCheck = "bla.blubb.Validator"
}

val List<String> composedChecks = newArrayList

/**
* Adds a validator that is to be executed additionally.
*
* @param composedCheckValidator
* name of a class extending {@link AbstractDeclarativeValidator}
*/
def void addComposedCheck(String composedCheckValidator) {
composedChecks += composedCheckValidator
}
