Replacement for TypeReferences.isInstanceof() [message #1402093]

Hi,

After upgrading from Xtext 2.4 to 2.6 we noticed that the method
org.eclipse.xtext.common.types.util.TypeReferences.isInstanceOf(JvmTypeReference, Class<?>)
has been removed.

We used this method to validate the JvmType references of our model (whether they implement certain interfaces).

What is the recommended way to do this kind of validation with Xtext 2.6?
I checked LightweightTypeReference.isSubtypeOf() but I had the impression that the environments in which this method is used are rather connected with Xbase.
Our grammar is not based on Xbase.

Thank you in advance,
Csaba

Hi Christian,

I did not try the "is" method, only looked at its implementation and from that it seems that it only checks qualified name equality. The implementation of the old "isInstanceOf" walked the superclass hierarchy and invoked "is" to find a match.

I also checked the commit that introduced the change to find out what is used now instead of the removed method (https://git.eclipse.org/r/#/c/21954/9), but could not find an Xbase-free usage.
