package soot.jimple.toolkits.pointer.nativemethods;
import soot.*;
public class JavaLangPackageNative extends NativeMethodClass {
    public JavaLangPackageNativeNativeHelper helper ) { super(helper); }

  
Implements the abstract method simulateMethod. It distributes the request to the corresponding methods by signatures.
  public void simulateMethod(SootMethod method,
			     ReferenceVariable thisVar,
			     ReferenceVariable returnVar,
			     ReferenceVariable params[]){
    String subSignature = method.getSubSignature();
    if (subSignature.equals("java.lang.String getSystemPackage0(java.lang.String)")) {
      java_lang_Package_getSystemPackage0(methodthisVarreturnVarparams);
      return;
    } else if (subSignature.equals("java.lang.String[] getSystemPackages0()")){
      java_lang_Package_getSystemPackages0(methodthisVarreturnVarparams);
      return;
    } else {
      defaultMethod(methodthisVarreturnVarparams);
      return;
    }
  }

  
java.lang.Package ***********************

  
This is an undocumented private native method, it returns the first (without caller) method's package. It should be formulated as a string constants. private static native java.lang.String getSystemPackage0(java.lang.String);
  public 
					     ReferenceVariable thisVar,
					     ReferenceVariable returnVar,
					     ReferenceVariable params[]) {
    .assignObjectTo(returnVar, Environment.v().getStringObject());
  }

  
private static native java.lang.String getSystemPackages0()[];
  public 
					      ReferenceVariable thisVar,
					      ReferenceVariable returnVar,
					      ReferenceVariable params[]) {
    .assignObjectTo(returnVar, Environment.v().getLeastArrayObject());
  }
