class TObjectSpy: public TObject

TObjectSpy, TObjectRefSpy

Monitors objects for deletion and reflects the deletion by reverting
the internal pointer to zero. When this pointer is zero we know the
object has been deleted. This avoids the unsafe TestBit(kNotDeleted)
hack. The spied object must have the kMustCleanup bit set otherwise
you will get an error.

Function documentation

TObjectSpy(TObject* obj = 0, Bool_t fixMustCleanupBit = kTRUE)
 Register the object that must be spied. The object must have the
 kMustCleanup bit set. If the object has been deleted during a
 RecusiveRemove() operation, GetObject() will return 0.
void RecursiveRemove(TObject* obj)
 Sets the object pointer to zero if the object is deleted in the
 RecursiveRemove() operation.
void SetObject(TObject* obj, Bool_t fixMustCleanupBit = kTRUE)
 Set obj as the spy target.
TObjectSpy(const TObjectSpy& s)
{ }
TObjectSpy& operator=(const TObjectSpy& s)
{ fObj = s.fObj; fFixMustCleanupBit = s.fFixMustCleanupBit; return *this; }
TObject * GetObject() const
{ return fObj; }
