How to find call hierarchy of a method

[Riyaz]

public class D {

public void myOwner(){
//i need to find the class who's calling me
}

public static void main(String[] args) {
new A();
new B();
new C();
}
}

class A {
public A() {
D d = new D();
d.myOwner();
}
}

class B {
public B() {
D d = new D();
d.myOwner();
}
}

class C {
public C() {
D d = new D();
d.myOwner();
}
}



In the above, in class D's myOnwer() i need an implementation which
tells who's calling the myOwner() i.e from class A or B or C

I also need the implementation to be compatible with Java 1.3

Any suggestions ?

public class D {

public void myOwner(){
//i need to find the class who's calling me

If you need this you have structured your application the wrong way.

There are ways that might work, though the 1.3 requirement makes it
harder. However, it is liable to be very messy, and definitely not
recommended.

Could you describe the design problem you are trying to solve? There is
almost certainly an easier way.

why not pass the owner as a parameter in the D constructor?

StringOutputWriter sw = new StringOutputWriter();
(new Exception()).printStackTrace(sw);
// parse the contents of sw to get the call stack

But I agree with the previous commenters; there's probably a better way to
do whatever it is you're trying to do.

You can declare a contructor in D, which takes a caller name as a
parameter.
Like,
public D(String name)
{
this.name = name;
}
Then, you can print this name.You should pass this name arg from A/B/C
while initializing the constructor. If you want to avoid hardcoding of
the classname, then do it like,
String thisClassName = this.getClass().getName();
then pass it to D's constructor like,
D d = new D (thisClassName);
