[forge-users] Roaster - how to get superClass typeArgments

[George Gastaldi]

You can use the "resolveType" method to resolve the FQN:

JavaClassSource source = Roaster
         .parse(JavaClassSource.class,
                   "import foo.bar.Talk;"
                  + ""
                  + "public class TalkService extends
CrudService<Talk, Long> {}");

String superType = source.getSuperType();
String firstType = Types.splitGenerics(superType)[0];
String resolvedType = source.resolveType(firstType);
System.out.println(resolvedType);// Returns "foo.bar.Talk"
