public class InstanceTracker
- extends java.lang.Object
Objects can register here when they are created.
This class notices when it an object is garbage collected
and keeps then track which instances are still running/alive.
One can configure for which classes one is interested
in seeing the created/removed delta.
This is meant for debug/development purposes, to verify
that cleanup is usually done properly, and not threads
or objects stay unintentionally referenced and never
get garbage collected.
So while editing/testing, one sets the "which one to see"
to the ones one want to monitor, but in productive use,
i.e. when checked in to svn, this should be set to
"don't show anything".
(perhaps with Java 1.5 or 1.6, or a good debugger one can
achieve the same effect, but I don't know how ;-)
