[opengoop] automatic call of destructor at garbage collection time

[Jim K. <ji...@ji...>]

I am trying to think of a way (preferably simple) to have the destructor
automatically called when object garbage collection occurs.  OpenGOOP =
object
data-stores are reentrant LV2 globals which are called by reference.  In
fact the object reference is a VI Reference.  When the call chain that
instantiated the object goes idle, the data store VI is garbage =
collected by
LabVIEW.  It would be nice to be able to intercept this and run the
destructor method of the object, automatically.  This would make =
debugging a
lot easier  In order to do this we would need to spawn a process that =
opens
a reference to the object LV2 global, so that it does not get garbage
collected.  Then we would need to poll the execution state of the =
top-level
VI in the call chain that instantiated the object.  When this top-level =
VI
goes idle we would then invoke the destructor.  What would make this =
much
easier, is if the event structure had a VI Event called "Going Idle" or
similar.

Any thoughts?
