I would like to trace allocations in my application. My sample application has this function: void f() { char[] c = new char[10]; int[] i = new int[10]; String s = new String("abc"); Object o = new Object(); } My probe method is annotated like this: @OnMethod( clazz = "eval.btrace.runner.TraceRunner", method = "/.*/", location = @Location(value = Kind.NEWARRAY, clazz = "int") //location = @Location(value = Kind.NEWARRAY, clazz = "/.+/") //location = @Location(value = Kind.NEW, clazz = "java.lang.Object") //location=@Location(value=Kind.NEW, clazz="/.+/") ) If run I like this, my method gets called if for allocation of int[] arrays. I I try however all the other commented location statements, nothing happens. Is there a possibility to trace all array locations as I tried using regular expression, is this supported? I was not able to get called for a object creation. How should I use Kind.NEW? I was looking for some detailled documentation of the @Location feature but was not able to find it. Can you help me? Thanks, Thomas |

Hi Thomas, the @Location.clazz attribute does not support wildcard type specification. If you think it would be useful feel free to file a RFE for such functionality. I've checked the location = @Location(value = Kind.NEW, clazz = "java.lang.Object") behavior as this kind of location specification should work ok. And, indeed, it does. Please, double check your code for any typos etc. Regards, -JB- |
