Comments:
The class RefCounterC is a reference counter which should be always inherited if a class contains pointers to allocated memory and the memory is shared by several objects. All constructors, a destructor, and an assigment operator must be modified in such class. The destructor is not virtual, therefore the class should be inherited as private or protected.

The RefCounterC class allocates its own memory separately from a memory of object.

BooleanT ToBeDeleted() const

Returns TRUE if the content should be deleted.

RCCountT Count() const

Returns the number of refrences to this object. NB. The following definition is now obsolete, The value 0 means there is no other reference to this object.

BooleanT IsSingleReference()

Tests is there is only one reference to this object.

LabelT Label() const

Returns the label of this reference counter.
The member function is useful mainly to recognize objects during debugging. The value of the label is uniquely defined pointer.
