Function documentation

TEveRefBackPtr(const TEveRefBackPtr& )

 Default constructor.

~TEveRefBackPtr()

 Destructor. Noop, should complain if back-ref list is not empty.

TEveRefBackPtr(const TEveRefBackPtr& )

 Copy constructor. New copy starts with zero reference count and
 empty back-reference list.

TEveRefBackPtr& operator=(const TEveRefBackPtr& )

 Assignment operator. Reference count and back-reference
 information is not assigned as these object hold pointers to a
 specific object.

void IncRefCount(TEveElement* re)

 Increase reference cound and add re to the list of back-references.

void DecRefCount(TEveElement* re)

 Decrease reference cound and remove re from the list of back-references.

void UpdateBackPtrItems()

 Call UpdateItems() on list of reverse references.
