IAssignabilityComputer [message #1059733]

Hello,

I have a code where there are these lines:

import org.eclipse.xtext.common.types.util.IAssignabilityComputer;

[...]

public class MyValidator extends AbstractMyValidator {

@Inject
IAssignabilityComputer typeComp;

[...]

The 'typeComp' attribute is to use the mthod 'isAssignableFrom'.
I suppose that now we should use isAssignable from the interface Type.
The problem is I use a JvmParameterizedTypeReference which is not a Type.

So is there an easy way to replace the IAssignabilityComputer ?

Do you think that this is code:

@Inject
TypeReferences typeRef;
[...]
JvmParameterizedTypeReference typeReference = ... ;
JvmParameterizedTypeReference typeReference2 = ... ;
if(typeRef.isInstanceOf(typeReference, Class.forName(typeReference2.getType().getIdentifier()))) { [...] }

do the smae thing as:

@Inject
IAssignabilityComputer typeComp;
[...]
JvmParameterizedTypeReference typeReference = ... ;
JvmParameterizedTypeReference typeReference2 = ... ;
if(typeComp.isAssignableFrom(typeReference, typeReference2)) { [...] }
