ILocationTrigger Interface

Provides access to properties and methods needed to manage action's location trigger. A location trigger allows developers to extend location based triggering of actions, e.g., extend location trigger to include crosses or departing / arriving.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

CoClasses that implement ILocationTrigger

CoClasses and Classes Description
ArrivingLocationTrigger (esriTrackingAnalyst) Controls the implementation of the action's location trigger for the geometrical arriving (entering) or departing (exited) a polygon.
CrossingLocationTrigger (esriTrackingAnalyst) Controls the implementation of the action's location trigger for the geometrical crossing of a polyline or a polygon border.
ProximityLocationTrigger (esriTrackingAnalyst) Controls the implementation of a proximity location trigger which can perform across multiple real-time point temporal feature classes.
