Detailed Description

This class defines SAMSON pointers, used to maintain references to a pointer target, i.e. objects of classes which derive from SBCReferenceTarget. Each SAMSON pointer may hold one reference at most. With SAMSON pointer indexes and SAMSON pointer lists, SAMSON pointers collectively form reference owners.

Unlike traditional C++ pointers, SAMSON pointers have two main characteristics:

they (collectively) own the reference target they point to: when the last reference owner is destructed, the reference target is deleted. In the data graph of SAMSON, objects may be created by some objects, SAMSON Elements, etc., and deleted by other objects, SAMSON Elements, etc. A SAMSON pointer will be automatically set to zero when the referenced object is deleted.
