Class InstanceTracker

  • 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 ;-)
