Question

I’m using Java’s Annotation Processing mechanism to create serializers for some of my classes.
I’d like to check each field of the currently processed class and make sure that it’s a subclass of MyBaseSerializableClass.
My problem is that i only know how to find the immediate super class of the field type:

TypeElement fieldType = (TypeElement)element;
TypeMirror superClassType = fieldType.getSuperclass();

How can i find the super class of superClassType and keep going up the inheritance tree until i hit Object ?

Answer 1

well i don’t know if this is the best way but this is the solution i found:

Types typeUtils = processingEnv.getTypeUtils();
while (!typeElement.toString().equals(Object.class.getName())) {
        element = (TypeElement)typeUtils.asElement(element.getSuperclass());
        // do whatever with element
}
