Retrieving STRING terminals in Xtend? [message #1743674]

Hello,

I'm currently working on a project which generates Java code using xtend, from a model which is created using a DSL I've produced in xtext. However I was wondering if it's possible to retrieve STRINGS from a resource, what I'm doing at the moment is using a tree iterator to get all the contents of a resource and looping through that list of objects. It's worked well so far but I have a rule in the grammar that looks like this,

Feature:
Feat | STRING;

Feat:
name = ID;

Now in another rule I have the following feature += Feature*

However when using the STRING option for the Feature rule, it doesn't get stored in the collection of Features when I attempt to retrieve it through the resource and I'm only able to access the Features which use the Feat option.

Is there a different way I have to go about accessing this information or is it just not possible?

Thank you.

You can use NodeModelUtils to access. The node model and iterate there as well.

BTW if the STRING. Is relevant why don't you asssign it?

Thank you Christian I will look into using NodeModeUtils.

The grammar was actually created by a colleague of mine so I will advise them to assign the STRING value.
