ASTVisitor Class Definition node

Question

I have been using the ASTVisitor class in Eclipse in order to take data at Method Declaration and Method Invocation nodes. I now also want to take data at Class Declaration nodes, but I can't find anything in the API for the ASTVisitor that would allow me to do this. Am I missing something? What would be a good way to do this?

Answer 1

If you want to get ClassDeclaration you should look for TypeDeclaration objects because:

A type declaration is the union of a class declaration and an interface declaration.

Once you found it you just have to use isInterface() method and if it returns false then it is ClassDeclaration.

Answer 2

The node "Class Declaration" that you are interested in is actually the TypeDeclaration, the node from which to take in the information that you need. For example:

• The list of modifiers ('public', etc.) allows you to figure out which and how many modifiers (node.modifiers ())
• The type of the super class, if it exists (node.getSuperclassType ())
• All the declarations of the methods
• etc

However, these are details that you need to build from a TypeDeclaration

However, both methods are inherited TypeDeclaration that can help you get all the info that you need to traverse the tree in a top-down approach.
