[cdt-dev] RE: How to Get The Scope of a Node
|
To find the references of a binding that is stored in the index, it
suffices to search the index: IIndex.findNames(...). You will also find
references made throug a macro expansion.
Local variables are not stored in the index, so you need to search the
ast:
IASTTranslationUnit.getReferences(..)
In case you want to find potential 'references' in comments or in
inactive code (#ifdef ...) you need to perform a text search as this is
done by the rename refactoring.
