Detailed Description

Derive your class from a PolymorphEvent to make it usable polymorphically. This just requires that your event subclass then define the send() pure virtual method, typically simply as

    struct ConcreteEvent: public PolymorphEvent
    {
        // ... your event-specific data and methods ...
        // ... and the override:
        virtual void send() const { sendTypedEvent(*this); }
    };

Member Function Documentation

virtual void PolymorphEvent::send (    )  [pure virtual]

Causes this event to be sent out to all listeners. The subclass must provide an override so the event can be used polymorphically. This allows you to have a container of PolymorphEvent's of unknown concrete types, e.g. to queue events of different types. Referenced by EventSender< PolymorphEvent >::send().

template<typename EvType> void PolymorphEvent::sendTypedEvent (  const EvType &    event )  [inline, static, protected]

The class derived from PolymorphEvent must override send() to make it call EventSender<EvType>::send(). It can also simply override it by making it call this method, sendTypedEvent, with *this. This method is really just a helper to simplify the syntax required for overriding send(). Definition at line 62 of file PolymorphEvent.hh.
