ArcObjects Library Reference (TrackingAnalyst)

CrossingLocationTrigger CoClass

Controls the implementation of the action's location trigger for the geometrical crossing of a polyline or a polygon border.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Tracking Analyst Extension.

Extended Error Information

Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.

Interfaces

Interfaces	Description
ICrossingLocationTrigger	Provides access to the action's location trigger specifically for the geometrical crossing of a polyline or a polygon border.
ILocationTrigger (esriCarto)	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.
ILocationTriggerAdmin	Provides access to properties and methods needed to configure location triggers for tracking actions.
ISupportErrorInfo	Indicates whether a specific interface can return Automation error objects.
