Foil 23 Interactions Represent Events in Time

From Overview of HLA and RTI DMSO Standards ARL Training Session IMT Dec 4 97 -- Dec 4 97. by Geoffrey Fox but selected by W. Furmanski from DMSO


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
