Thanks very much for this info, Doug!
That gives us something to look at.

I’ll try my best. But essentially,
the CModel does not provide information like this. The CModel really just
provides a table of contents to the source. What you are more interested
in is the index that links function calls to their definitions. The CModel
and the DOM/index are pretty much unrelated.
Unfortunately we don’t really
have documentation available to describe how to do this. You may want to
look how the FindAction works. This action implements the search actions
in the Outline view amongst other things. We only map to source locations
for the references, though and do not map directly to scopes. This will
probably be added when we add the Call Hierarchy view in CDT 4.0.

Hi all,
Would anyone be able to answer the query from Jagan's e-mail below?
I also have some questions in addition to Jagan's, the set-up of interest
being Eclipse 3.1.2 / CDT 3.0.2, for the moment:
1) First of all, is CModel actually capable of giving you this type of
information easily (without your own code having to do some parsing itself)?
If not, then is there some other mechanism via which to achieve this, e.g.
by querying the DOM/AST directly? (Is the DOM even used in CDT 3.0.2?)
Or would the best option be to do some parsing using the CDT parser (IParser)?
2) As I understand it, the CModel hierarchy is wrapped around the indexer
somehow. Is this true?
I realize that these are a lot of questions. However, as there isn't much
documentation on the CModel, DOM and indexer on the CDT WIKI or source
code, any answers would be greatly appreciated.
Many thanks,
Deniz

| [cdt-dev] How to find find the scope
of a function/variable usage. |

I am using CModel
Given a function usage (org.eclipse.cdt.core.model.IFunction) within some
translation unit, how does one obtain the scope within which this function
is called?
SomeScope::someMemberFunction {
foo();
}
2) Given a function usage, where the function is called explicitly on an
object, how does one obtain the scope of this function call, i.e. the type
of the variable that the function is called on?
SomeScope::someMemberFunction {
someVariable->foo();
someVariable2.foo();
}

Jagan
