@victorjmarin @crrivero CAN YOU PLEASE ASSIST ME IT IS VERY IMPORTANT FOR MY PROJECT

Would it be possible to add a license to this project? I would really like to use your code in one of my projects. Here is how to do it: https://stackoverflow.com/a/31666878

Hi, great work!
I'm trying to extract all data sharing dependence between nodes in the PDG. With data sharing I mean that if I have two statements S1 and S2, if they both appear in the same execution path thus they share some data, for example:
If I have this code

public void main() {
        String str = read();
        boolean valid = isValid(str);
        if (valid) {
            foo(str);
        } else {
            bar(str);
        }
    }

the function read is linked to: isValid, foo and bar because data dependence (i.e. I found and Edge of type Data in the PDG), but I need to track also that the function isValid is linked to foo and bar because data sharing. Indeed the result of isValid choose which function call.
Can you help me with that?
Thank you

Hello, I am currently doing program analysis work on Java function level. How can I use sourcedg to generate a function level dependency graph? Thank you.

Hii,

I am trying to generate Program Dependence Graph using sourcedg. When I tried executing the file Test.java I got the exception "Exception in thread "main" com.github.javaparser.ParseProblemException: (line 1,col 10) Parse error. Found "int", expected one of ";" "@" "class" "enum" "interface" "module" "open""
Below is the code for which I am trying to generate the PDG
`public static int srch()
{
int c, first, last, middle, n, search, array[];
first = 0;
last = n - 1;
middle = (first + last)/2;

while( first <= last )
{
  if ( array[middle] < search )
    first = middle + 1;
  else if ( array[middle] == search )
  {
    return middle+1;
  }
  else
     last = middle - 1;

  middle = (first + last)/2;

}
if ( first > last )
return 0;
}
`

And the stack trace is:

Exception in thread "main" com.github.javaparser.ParseProblemException: (line 1,col 10) Parse error. Found "int", expected one of ";" "@" "class" "enum" "interface" "module" "open"

hello,i would like to learn this project,but i can only find one implementation.

How to use sourcedg to perform dependency graph analysis on a jar file or all java files (source code) in a folder
