1220865 - add ability to search for callers, etc. of class template methods

Status: RESOLVED FIXED

(Webtools Graveyard :: DXR, defect)

Description

[Nathan Froyd [:froydnj]]

Head to:

https://dxr.mozilla.org/mozilla-central/source/xpcom/glue/nsCOMArray.h#292

(the definition of the InsertObjectAt method, but any method in nsCOMArray<T> will do)

Try to search for callers, which gets you to this URL:

https://dxr.mozilla.org/mozilla-central/search?q=%2Bcallers%3A%22nsCOMArray%3A%3AInsertObjectAt%28T+*%2C+int32_t%29%22

which is not quite correct.

What I really want in this case is all instantiations of nsCOMArray<T>::InsertObjectAt(T*, int).  I suppose the same sort of logic would apply to template functions as well.

Another related issue is that when you want to search for, e.g., all other references to something like nsBaseHashtable::EnumerateRead based on a variable foo.EnumerateRead, the search for references link substitutes the values of template parameters.

Template specialization and partial specialization provide interesting corner cases, and I can see wanting to search for references/callers of templated methods that don't refer to the specialized method bodies. Arguably, it might make sense to overload override/overridden to get at specialization information.
