1 | An interaction represents an event in time that has no continuing state, e.g. a change in an ATC clearance or the firing of a weapon |
2 | An interaction, unlike an object does not persist; it occurs at a specified time |
3 | Federations subscribe to classes of interactions. They are then notified when another federate sends an interaction of that class |
4 | Each interaction class specifies the set of parameters for each instance of that class |
5 | Like object classes, one interaction class can inherit from another |
6 | An interaction is instantiated by messages which are essentially sent and received by methods of objects |
