Mining sequence of method calls

[otmarjr]

Hello folks !!

Currently I'm working in a project where I'd like to extract sequences of method calls for a given class from the source code. Could you please tell me if this is possible using Boa infrastructure ?  I'm mostly interested in Java projects using JDK's classes.

Best regards,

Otmar

Hi Otmar,

By ‘sequence of method calls’ I assume you mean on a per-method basis?  In other words, some method has some specific sequence (although with branching, it isnt actually a fixed sequence but rather a set of sequences/paths) of method calls?

If so, this is definitely possible!  You just want to have a visitor for the Method type, and then build a list of all seen Expression nodes that are calls.

Hello Dr Dyer,

Thanks for taking your time to answer. In fact, I'd like to make just one restriction, which would be consider the possible sequences in a per-class basis. For example, given a variable in a class, I'd like to create the set of all possible sequences of method calls that can occur after executing public methods of the class under analysis. Hopefully, it would be possible to account for branches caused by if stataments or exception handling.

Kind regards,
Otmar

Hello Mohammad,

Glad to see that you've noticed I'll have some challenges in picking an algorithm to mine the classes! Could you please tell me if Java Parser could be integrated with Boa ? Could you please point me in the direction of any algorithm to derive the set of sequences of method calls, given the AST of a class ?

Best regards,
Otmar

Hi Otmar,

In that case, you probably want to still mine on a per-method basis.  Then you can compose each (public) method to build all possible sequences out of that.

Hello Robert,

Ok, I'll give it a try with Boa. Glad to hear it supports such use cases.

Best regards,

Otmar
