Description

The LinkTarget class template stores a list of Link objects that each currently point to the object of which the LinkTarget class is a base class. A class of type T inherits from LinkTarget<T> to allow it to be the target of an object of type Link<T>. When the LinkTarget object is destroyed, all of the links currently pointing to it are automatically cleared to nullptr.
