Dear Bharat,
You are asking a very valid question. Having invocations between C / C++ functions would be great to have.
Kind of related, we did some assessment of the includes between .c, .h, .cpp, .hpp files. We were able to do a graph as:
Each circle is a file, and arrow are includes relationship. Size is the number of lines of code. Color indicates part of an architecture.
But yes, it would be great to have the control flow between functions, even an approximation.
Cheers,
Alexandre

many thanks for confirming i can post this query here. I was talking about something like the xref screen shot at
http://sourcenav.sourceforge.net/screenshots/
I used this for C/C++ projects long back.. Not sure if pasting that png is a good idea.
The current project I work on has a big code base. When i say 'understand code flow' I would like to write a query that will return the chain of all methods invoking a particular method as well the methods this will invoke.
Simple scenario: Suppose there exists a set of classes having particular methods as show below:
AC::AMethod -> BC::BMethod -> CC::CMethod -> DC::DMethod -> EC::EMethod
To serve a client call for a particular scenario, the entry point from client code is Amethod in Class AC.
This in turn invokes BMethod of BC,
which invokes CMethod of class CC,
which invokes DMethod in DC
then finally invoked EMethod of class EC and returns to the client code.
The query/queries when given method name CC::CMethod should return
AC::AMethod -> BC::BMethod
and
DC::DMethod -> EC::Emethod
In an actual code base, chances are that there are multiple code flow paths invoking CC::CMethod and multiple methods invoked by CC::CMethod. All these paths that represent different scenarios should be reported. This should help delete all possible dynamic interactions at method level. Currently (I think) I know how to do this at a class level using moose model.
Regards,
Bharat

Content-Type: text/plain; charset="utf-8"
This is more like a user question. But do not know of moose-users mailing
list. Apologies if there is one.
I recently started exploring moose model, tried out the example at the
moosebook site using ArgoUML and some of my own java projects(imported
using jdt2famix. And am fairly comfortable with the features described in
the moose book.
Question:
Can i use the same to understand code flow ? I see there are methods to get
a FAMIXMethod's invoked by and invokes methods. But there are no concrete
example for analysing code flows. Has anyone tried this? or is it possible
at all.
Regards,
Bharat

Hi,
First of all, welcome. This is the correct mailing list :).
Could you detail what you mean by code flow? It is best to pick a particular case study and a very specific problem and work from there. Could you describe such a specific problem?
Cheers,
Doru
