Is there a way to debug how many references exist to an object? Something like System.ObjectRef( object ); [edited by - spyder on January 14, 2003 3:55:06 PM]

If you are trying to do this to force Garbage Collection, wont work. Garbage Collection in java is handled by the VM and you can only ''suggest'' it to occur in your apps.

You need to build that yourself. Create a static variable that is initialized to 0 and is increased every time the constructor is called. Then you decrease it every time finalize() is called. Finalize is called by the garbage collector.

First make it work,
then make it fast.

//Spyder, get rid of the "<object>" in your post.  It is being

//This was put in source tags to prevent further problems.

I''m not trying to force garbage collection, merely trying to find a smart way to keep track of all references to an object so that I can nullify them.

Why do you need to nullify the objects in the first place?
