Thanks for looking into this. Would be cool to get this supported after the
proposal is finalized.
================
Comment at: clangd/Protocol.h:891
+
+ std::vector<TypeHierarchyResult> Parents;
+
----------------
What is the proposal to add children (i.e. overriden methods) to the hierarchy?
This seems like a place where we might want to have multiple requests from the
clients when expanding the nodes.
================
Comment at: clangd/XRefs.cpp:669
+ const CXXMethodDecl *Candidate) {
+ // FIXME: How do I determine if Method overrides Candidate?
+
----------------

See the code that actually computes a list for `override_methods()`:
Sema::AddOverriddenMethods.
================
Comment at: clangd/XRefs.cpp:732
+ // If this is a variable, use the type of the variable.
+ CXXRD = VD->getType().getTypePtr()->getAsCXXRecordDecl();
+ } else if (Method) {
----------------
Why special-case the variables? Maybe just return empty results for consistency
with other use-cases (typedefs, etc)?
================
Comment at: clangd/XRefs.cpp:741
+ if (CXXRD)
+ return getTypeHierarchy(CXXRD, Method, SourceMgr);
+
----------------
Maybe also return all base types for classes?
