Will this free up memory correctly?

Hi,

If I have a TParticle Type that I create an instance of, and I also have an instance of a TTracker type that has a TParticle field which I point to the instance of the TParticle, then I add the instance of the TTracker Type to a list (still with me?) then later on I do List.Remove(t) where t is my TTracker type instance, will the field within it which points to the TParticle type be freed so that the TParticle will now be freed by the garbage collection properly? I hope so. Trying to think how I can diagram this in text. Anyway here's some example code (tested it compiles):

Type TParticle
End Type

Type TTracker
  Field p:TParticle
End Type

Type TTrackerList extends TList
  Method AddNew:TTracker(p:TParticle)
    Local t:TTracker = new TTracker
    t.p = p
    AddLast(t)
    return TTracker
  End Method
End Type

Global trackerlist: TTrackerList = new TTrackerList

Add()
Remove()

Function Add()
  local p:TParticle = new TParticle
  trackerlist.addnew(p)
End Function

Function Remove()
  For t:TTracker = eachin trackerlist
    trackerlist.remove(t)
  Next
End Function

I know I could code this a different way, but I need it this way for a specific purpose and I just want to check that the memory will be freed up properly. Any ideas?

Thanks.
