Kai Müller commented on ROASTER-4:
----------------------------------

Hi, I need some help with jdt:
I currently try to add the generic type to a class with this code, but it fails, because the simple name if the class has already a parent, which I can't delete.


{code:java}
      ParameterizedType pt = body.getAST().newParameterizedType(
               body.getAST().newSimpleType(getBodyDeclaration().getName()));
      org.eclipse.jdt.core.dom.Type t = fromString(Types.toSimpleName(clazz.getName()), body.getAST());
      System.out.println(t);
      pt.typeArguments().add(t);
{code}


{code:java}
final JavaClassSource javaClass = Roaster.create(JavaClassSource.class);
      javaClass.setName("Teest");
      javaClass.addGenericType(String.class);
      System.out.println(javaClass);
{code}

Can somebody please assist how to do this? I basically want to have "public class Test<String>{}"

BR,
Kai

> For a constraint, I need to implement a parametrize interface like this :
> {code}
> public class MaxValidatorForString implements ConstraintValidator<Max, Number> {
> {code}
> The only way I could find is by passing a String :
> {code}
> final JavaClassSource javaClass = Roaster.create(JavaClassSource.class);
> javaClass.setName("MaxValidatorForString");
> javaClass.addImport(ConstraintValidator.class);
> javaClass.addInterface("ConstraintValidator<Max, Number>");
> {code}
> It's a shame because with {{addInterface(Class)}}, it does the import automatically and things are more typed. But I cannot add types :
> {code}
> final JavaClassSource javaClass = Roaster.create(JavaClassSource.class);
> javaClass.setName("MaxValidatorForString");
> javaClass.addInterface(ConstraintValidator.class);
> {code}
> It would be good to have something like :
> {code}
> javaClass.addInterface(ConstraintValidator.class).addType(Max.class).addType(Number.class);
> {code}
