The generic logic defined in this class template and invoked applies to + //! all event types defined in the library and boils down to the following: + //! 1. + //! a. If EventT has TypeId defined (which normally is a case of + //! all leaf - specific - event types, via QUO_EVENT macro) and + //! \p type doesn't exactly match it, nullptr is immediately returned. + //! b. In absence of TypeId, an event type is assumed to be a base; + //! its derivedTypes are examined, and this algorithm is applied + //! recursively on each. + //! 2. Optional validation: if EventT (or, due to the way inheritance works, + //! any of its base event types) has a static isValid() predicate and + //! the event JSON does not satisfy it, nullptr is immediately returned + //! to the upper level or to the loadFrom() caller.
