public class CallStack
extends java.lang.Object

This class is part of the Java Tools (see http://mpii.de/yago-naga/javatools). It is licensed under the Creative Commons Attribution License (see http://creativecommons.org/licenses/by/3.0) by the YAGO-NAGA team (see http://mpii.de/yago-naga). This class represents the current position of a program, i.e. the stack of methods that have been called together with the line numbers.
Example:

   public class Blah {
     public m2() { 
       System.out.println(new CallStack());   // (1)
       System.out.println(CallStack.here());  // (2)
     }

     public m1() { 
       m2(); 
     }

     public static void main(String[] args) { 
       m1(); 
     }
   }
   -->
      Blah.main(12)->Blah.m1(8)->Blah.m2(2)  // Call Stack at (1)
      Blah.m2(3)                             // Method and line number at (2)

Constructor Summary

CallStack()
Constructs a call stack from the current program position (without the constructor call)

Method Summary

boolean	equals(java.lang.Object o) Returns TRUE if the two call stacks have the same elements
java.util.Stack<java.lang.StackTraceElement>	getCallstack() Returns the callstack
static java.lang.StackTraceElement	here() Gives the calling position
static void	main(java.lang.String[] args) Test routine
CallStack	ret() Pops the top level of this callstack, returns this callstack
java.lang.StackTraceElement	top() Gives the calling position as a StackTraceElement
java.lang.String	toString() Returns "method(line)->method(line)->..."
static java.lang.String	toString(java.lang.StackTraceElement e) Returns a nice String for a Stacktraceelement
