IndoorsLocationDataSource

Provides an indoor or outdoor position based on device sensor data (radio, GPS, motion sensors). An IPS (indoor positioning system) position is calculated based on radio data and motion sensors. The GPS position is used as a fallback in case an IPS position can't be calculated, or if the IPS position reports a position outside of a building.

constructor(positioningTable: FeatureTable, pathwaysTable: ArcGISFeatureTable? = null, levelsTable: ArcGISFeatureTable? = null, positioningId: Guid? = null)

Create a new IndoorsLocationDataSource from the given feature table and row in the "IPS_Positioning" FeatureTable. See the ArcGIS IPS Information Model for more information.

constructor(definition: IndoorPositioningDefinition)

Creates a new IndoorsLocationDataSource object using the information contained in the provided IndoorPositioningDefinition. For a map to be IPS-aware, one of the following must be true:

Invoked when there is a new info message. If IndoorsLocationDataSourceConfiguration.areInfoMessagesEnabled is set to true, IndoorsLocationDataSource sends additional messages that are otherwise not forwarded to the user. These messages may be useful for diagnosing issues and troubleshooting. Enabling this setting is meant for debugging purposes and might negatively affect performance.

val warning: StateFlow<Throwable?>

An error that describes a problem encountered while starting or running the LocationDataSource. This property is used to notify user about transient, non-terminal errors, which occur in IndoorsLocationDataSource. Such errors can influence accuracy of the final positioning. Information stored inside reported error contains useful information about its origin. Unlike LocationDataSource error it does not require IndoorsLocationDataSource to be restarted.
