如何使用ASTParser从Java文件中检索超类名称？

Question

I need to retrieve SuperClass name of a java file (which extends a class, i need that class name). In order to do this, I began to use ASTParser but I'm newbie so any example or illustration can be helpful. I use ASTView to comprehend which ways that AST keeps a java file structure but I'm stuck while trying visit(), endvisit() functions. I could not find any detailed example.

Thanks in advance...

Answer 1

You didn't say much of how far you had got already.

In the visitor, override visit(TypeDeclaration node) and then, on the node, call getSuperclassType() .

If you return true the parsing will continue inside the type declaration, otherwise it stops.

Answer 2

Could you use the getSuperClass() method of the Class class in your code instead?

getSuperClass()

Answer 3

This code will work..

IType type = ...;

ITypeHierarchy  a = type.newSupertypeHierarchy(new NullProgressMonitor());
        IType[] superTypes =  a.getAllSupertypes(type);
        if(superTypes.length == 1 && superTypes[0].getKey().equals("Ljava/lang/Object;")){
            this.isSuperClassObject = true;
        }
        else{
            this.isSuperClassObject = false;
        }
