49    @brief
50        A NotificationDispatcher is an entity that, upon being triggered, dispatches (or sends) a specified @ref orxonox::Notification "Notification".
51
52        There are two parameter to be set:
53        - 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.
54        - The @b broadcast . Specifies whether messages are broadcast (i.e. sent to all clients) or just sent to a specific player.
55
56        Its standard usage is:
57        @code
58        <NotificationDispatcher sender="me">
59            <events>
60                <trigger>
61                    <PlayerTrigger />
62                </trigger>
63            </event>
64        </NotificationDispatcher>
65        @endcode
66        But keep in mind, that NotificationDispatcher is an abstract class.
67        Also 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".
68        If the NotificationDispatcher is not set to broadcast only events caused by @ref orxonox::PlayerTrigger "PlayerTriggers" trigger a message since the information obtained by the @ref orxonox::PlayerTrigger "PlayerTrigger" is used to identify the client to which the message should be sent.
