Detailed Description

template<typename ClassType, typename SubjectType>
class MAKLogger::DtObserverFunctor< ClassType, SubjectType >

ObserverFunctor is an observer implemented via Functor object which will call an object's member function.

The ObserverFunctor should be used with Value semantics (ie a value member of the calling object) however they are not copyable and this is since if the owner object is copied the copy's functor will need to be reassigned.

Warning: If the calling object life time is less than the Functor object calls will result in seg-faults. Solution is to have the calling object be the owner of the Functor which should ensure this condition.
