Re: [jdt-debug-dev] StackFrames and Variables

From the description provided, it sounds like you are doing the right 
thing to avoid suspending the thread.

We have tests that demonstrate this behavior (see 
org.eclipse.jdt.debug.tests plugin - JavaBreakpointListenerTests). To be 
sure, I added a test for method breakpoints, and it all seems to be 
working. Perhaps you could provide us with a test case or small example 
that demonstrates the problem you are having (i.e. code that we can use to 
replicate the problem)?

Subject
[jdt-debug-dev] StackFrames and Variables






In the course of trying to record some information when debugging I have 
an implementation of IJavaBreakpointListener. When my 
JavaMethodBreakpoints are hit I simply printout some information to the 
console. My breakpoints have been set up to not suspend execution of the 
  debugee.

I have the following code to print out some information:

System.out.println
("<METHOD=\""+breakpoint.getMarker().getAttribute("METHOD").toString()+"\" 

");

System.out.print
("SIGNATURE=\""+breakpoint.getMarker().getAttribute("SIG").toString()+"\" 
");

System.out.print
("LINE=\""+breakpoint.getMarker().getAttribute(IMarker.LINE_NUMBER).toString()+"\"/>");

IJavaStackFrame[] frames = (IJavaStackFrame[]) thread.getStackFrames();
   for(int i=0;i<frames.length;i++){
       List variables = frames[i].getArgumentTypeNames();
       Iterator iter = variables.iterator();
           while(iter.hasNext()){
             System.out.println
                     ("<VARIABLE =\""+iter.next().toString()+"\"/>");
             }
    }

This is contained in my breakpointHit(..) method that always returns a 
result of IJavaBreakpointListener.DONT_SUSPEND. However this code seems 
to suspend the execution of the debugee. I launch the debugee by using 
the Debug As.. button in the Run-time Workbench, before this would 
execute the debugee without suspending the execution when the 
breakpoints were hit.

How can I get the information from StackFrames, Variables and their 
Values without suspending the execution of the debugee?

TIA for any help anyone can provide

Joe

(Note: I know the information for method/signature can be returned from 
the breakpoint itself, however I have annotated other information to the 
marker that I use it's just not shown here)
