(e.g. @ref orxonox::Notification "Notifications" were added or removed) 74 When inheriting from a NotificationListener it is important to register (in the constructor) and unregister (in the destructor) it to and from the @ref orxonox::NotificationManager "NotificationManager". 81 The NotificationListener interface (or more precisely abstract class) presents a means of being informed when a new @ref orxonox::Notification "Notification" is sent. 82 The NotificationListener can be used to send a new notification message (with NotificationListener::sendNotification() ) or a new notification command (with NotificationListener::sendCommand() ). Each NotificationListener is then informed about the new @ref orxonox::Notification "Notification" and can take appropriate action. Currently the only NotificationListener ist the @ref orxonox::NotificationManager "NotificationManager" singleton. 83 84 When inheriting from a NotificationListener it is important to provide an appropriate implementation of registerNotification() and executeCommand(). 75 85 76 86 @author … … 78 88 79 89 @ingroup Notifications 90 @todo Consistent terminology between message, notification and command. 80 91 */ 81 92 class _OrxonoxExport NotificationListener : virtual public OrxonoxClass … … 84 95 NotificationListener(); 85 96 virtual ~NotificationListener() {} 97 98 /** 99 @brief Sends a Notification with the specified message to the specified client from the specified sender. 100 @param message The message that should be sent. 101 @param sender The sender that sent the notification.
