Monitoring a vector

Question

Hi all
Been too busy to post recently, but have a problem that I want to debug and need some help on how to do it.
I am reading an xml file and creating some objects based on it's contents, and then storing these objects in a vector. I am then writing out all of the contents of the Vector (again in XML). What I have found in debugging is that I am reading 3 objects, and they are quite happily added to the vector. However, when I come to write out said vector some other piece of code has modified it and it seems there is only 1 element left ( the first).
What I would like to do is add some sort of monitor to the vector so that I get a notifocation of when it's size changes ( or when something is added/removed ), and then try to work out what caused it to resize. Can I do this without creating a MyVector class that overrides some of the methods of Vector?

So you want to change the behavior of Vector without creating a subclass? I suppose you could change the source to Vector and recompile it, but yuck.
Do you have access to a debugger? You could throw the whole thing on a debugger and put a breakpoint at Vector.remove, etc.
