Detailed Description

Interface of a reference counter.

The reference counter allows a class instance to know the number of references on it. When this number reaches zero, it means that the instance is no longer used. This system is used primarily to automatically free memory when the number of references drops to zero.

This class is used through classes like AutoRefT which allow automatically incrementing or decrementing the counter of the objects they point to.
