Detailed Description
template<typename T>
class observer::BasicChangeContext< T >
Basic change context template class.
Simplest subclass from IChangeContext. It holds previous value of changed one. This value is wrapped by smart pointer to keep clear instancion policy.
Exception NOTE: No method throws an exception.
