49    @brief
50        A NotificationDispatcher is an entity that, upon being triggered, dispatches (or sends) a specified @ref orxonox::Notification "Notification".
51
52        There is one parameter to be set, the @b sender . The sender specifies the part of Orxonox the sent @ref orxonox::Notification "Notification" comes from. The default value is set by the classes implementing NotificationDispatcher.
53
54        Its standard usage is:
55        @code
56        <NotificationDispatcher sender="me">
57            <events>
58                <trigger>
59                    <PlayerTrigger />
60                </trigger>
61            </event>
62        </NotificationDispatcher>
63        @endcode
64        But keep in mind, that NotificationDispatcher is an abstract class and in this example @ref orxonox::PlayerTrigger "PlayerTrigger" stands for any event that is caused by a @ref orxonox::PlayerTrigger "PlayerTrigger", so instead of @ref orxonox::PlayerTrigger "PlayerTrigger", there could be a @ref orxonox::DistanceTrigger "DistanceTrigger", or a @ref orxonox::DistanceMultiTrigger "DistanceMutliTrigger", or even an @ref orxonox::EventListener "EventListener" that waits for an event coming from any kind of @ref orxonox::PlayerTrigger "PlayerTrigger".
