Problem in finding class name and the associated file name

[Parvez]

For my research I am trying to find user defined exception classes including the file name containing those classes:

Please see the following code:

p: Project = input;

myout: output collection [string][string][string] of int;

file_name: string;

code_repo: string;

class_name:string;

visit(p, visitor {

    

 before node: CodeRepository -> {

            code_repo = node.url;

            snapshot := getsnapshot(node, "SOURCE_JAVA_JLS");

            

            foreach (i: int; def(snapshot[i])){

                file_name = snapshot[i].name;

                visit(snapshot[i]);

            }

    }

 

 before n: Declaration ->{

 

    #I am looking those classes that are extend from Exception class

    if(n.kind == TypeKind.CLASS && def(n.parents) && len(n.parents) > 0 && match(`Exception`, n.parents[0].name)) {

         myout[code_repo][file_name][n.name] << 1;

    }

 }

 

    

});

Here is the first few lines of output:

myout[https://github.com/1mobilesuper/1mobile_download.git [src/me/onemobile/android/download/DownloadThread.java][GenerateSaveFileError] = 1

myout[https://github.com/1mobilesuper/1mobile_download.git][src/me/onemobile/android/download/Helpers.java][GenerateSaveFileError] = 1

myout[https://github.com/AlexCaranha/JWavRecorder.git][src/JWavRecorder_Model/WavFileException.java][WavFileException] = 1

myout[https://github.com/AlexCaranha/JWavRecorder.git][src/Model/ISignal.java][WavFileException] = 1

myout[https://github.com/AlexCaranha/JWavRecorder.git][src/Model/ISignal.java][WavFileException] = 1

myout[https://github.com/AlexCaranha/JWavRecorder.git][src/Model/ISignal.java][WavFileException] = 1

I can find the class names but I am receiving the same class names multiple times associated with different source files. Can you point me what is wrong in the code? (For example, the WavFileException class is defined in WavFileException.java not in the ISignal.java)

You need to add a ‘stop;’ statement after the foreach() block in your CodeRepository visit clause.

Otherwise, you manually visit each snapshot and then *also* do the default traversal which visits *every* node in the tree (using the last snapshot’s filename).
