RE: [cdt-dev] Finding references using PDOM and then finding the AST elements that contain the reference..

Um, sure. You can resolve the binding for the IASTName using the IPDOMResolver interface, or if you know it is a PDOMName, simply invoke it’s resolveBinding method. That will give you the binding. From there, you can navigate the IBinding hierarchy like you would with the DOM. And when doing that, please use the IBinding interfaces if at all possible since the PDOM classes are and will remain internal and are subject to change. If there are interfaces missing for PDOM specific info, we’ll add new interfaces for that in 4.0.

Oks..maybe not exactly the AST per se...I saw in the code that when we add IASTNames to the PDOM we add stuff like PDOMCPPField, PDOMCPPBase etc...if there is a way of getting to these from the PDOMName that is returned as the reference it would be good enough for me so that I save on recreating the AST and walking over it.
