How to get rid of the unrelated classes when using WALA to analyze Java bytecode? -


i read aricle wala on http://www.programcreek.com/2012/10/wala-tutorial/ , try execute example. want know how rid of classes except test code within test.jar. thank you!

import java.io.file; import java.io.ioexception; import java.util.jar.jarfile;  import com.ibm.wala.classloader.iclass; import com.ibm.wala.classloader.imethod; import com.ibm.wala.ipa.callgraph.analysisscope; import com.ibm.wala.ipa.cha.classhierarchy; import com.ibm.wala.ipa.cha.classhierarchyexception; import com.ibm.wala.ipa.cha.iclasshierarchy; import com.ibm.wala.util.config.analysisscopereader; import com.ibm.wala.util.io.fileprovider;   public class walatest {     public static void main(string args[]) throws ioexception, classhierarchyexception {              file exfile=new fileprovider().getfile("java60regressionexclusions.txt");             system.out.println(exfile.getabsolutepath());             analysisscope scope = analysisscopereader.makejavabinaryanalysisscope("test.jar",exfile);             iclasshierarchy cha = classhierarchy.make(scope);             (iclass c : cha) {                 string cname = c.getname().tostring();                 system.out.println("class:" + cname);                 (imethod m : c.getallmethods()) {                     string mname = m.getname().tostring();                     system.out.println("  method:" + mname);                 }                 system.out.println();             }       } }

in loop of iclass, add following line check scope first using isapplicationloader(). 

if (!scope.isapplicationloader(c.getclassloader())) continue;
