caller info

Class A creates an object of Class B and uses that object to instantiate a method C. How can i tell inside method C that 'this' was called by A?

Inside class A:

B bbb = new B();
bbb.doSomethingClever();

Inside class B:
inside doSometihngClever () {
I got called from class A ... <-- how can i get this information?
}

Maybe the following can be of any help:

public class AAA {
	
	public static void main(String[] args) {

		new BBB().method();
	}
}

class BBB {
	
	public void method() {
		Exception ex= new Exception();
		ex.fillInStackTrace();
		StackTraceElement[] ste= ex.getStackTrace();
		
		for (int i= 0; i < ste.length; i++)
			System.out.println(ste[i].getMethodName()+" in "+ste[i].getClassName()+" at line "+ste[i].getLineNumber());
	}
}

Note that the JVM is free to skip StackTraceElements (thanks to call optimizations).

kind regards,
