Extracting the parameters from (Calls) [message #1810585]

Hello, Eclipse community,

I have a problem getting something from the KDM, from calls to be exact.
I'm building a call graph. so i need the methods called (by whom and parameters passed if they exist ).
Let's say method A calls method B(X).
I can get the parameters (X) passed to method B but i also want to know the parameters used to invocate the method A before as well.
So, at the end, i will have with something like this ... -> Method A(Args_A) -> Method B (Args_B) -> ....

I need to extract those parameters to distinguish multiple methods with the same name but different parameters.

I'm not sure if MoDisco allows this or not. so any help is appreciated.
Thank you !

Hello Amine,

Have you read the KDM metamodel specification?.

12.7.7 ParameterUnit Class
ParameterUnit class is a concrete subclass of the DataElement class that represents a formal parameter; for example, a formal parameter of a procedure. ParameterUnits are owned by the Signature element. Instances of ParameterUnit class are endpoints of KDM data relations that describe ccess to formal parameters. (https://www.omg.org/spec/KDM/1.4/PDF)

Maybe thats help you,

Regards,

Daniel
