Symbol API and mapping from Symbol to PsiElement
Answered
Hi,
I'm trying to write some basic plugin for a custom language but I have not understood exactly how the “Go to declaration” works. I have implemented my `getOwnReferences()`, `getOwnDeclarations()` and my `Symbol` subclass with `equals()`, etc implemented. Do I need to implement and register some service to allow the IDE to map from the `Symbol`s to the `PsiElement`s to navigate correctly?
I got a very simple test with `PsiReference` to work previously and perhaps the Symbol API is not supposed to be used at all by plugin devs?

Hi,
Please share your implementations.

The code is messy as I've been experimenting to try to figure things out. Basically my `Cpp2PsiValueDeclaration` implements `PsiSymbolDeclaration` and my `Cpp2PsiIdentifier` implements `PsiSymbolReference` and both these classes are what the grammar instantiates when building the PSI.
I think a short description of how the mapping between `Symbol` and `PsiElement` is supposed to be done could clarify a lot for me.
