Hi Freddy,
Thank you very much for your help. I am sorry because I did not explain a
lot of thinks but I only want to obtain information about source code to
calculate new metrics. For example, I want the number of methods of a
measured class that overrriden methods from a base class. For this reason,
I want to obtain the AST.
Thank you.
Regards,
M=EDriam

Hi, <br><br>I have been looking Squid plugin because I want an abstract
