Class ReferenceInspector

java.lang.Object
  net.wotonomy.ui.swing.ReferenceInspector

All Implemented Interfaces:

java.awt.event.ActionListener, java.awt.event.MouseListener, java.util.EventListener

public class ReferenceInspector
extends java.lang.Object
implements java.awt.event.MouseListener, java.awt.event.ActionListener

ReferenceInspector tracks objects until they are garbage collected. Use it to track objects that you suspect are not being GCed. ReferenceInspector retains only weak references to the objects that it tracks, so when those weak references cannot be resolved, the object has been garbage collected. Note that under some GC implementations, adding a weak reference to an object will delay garbage collection for that object.
