DataSourceChangedNotifier

interface DataSourceChangedNotifier

Interface for the notification of changes in the data source. It allows the subscription to data source changes and enables reaction to them.

The DataSourceChangedNotifier instance provided by the com.tomtom.sdk.datamanagement.hybridnavigationdata.HybridNavigationDataStore is tied to the lifecycle of the data store. Once the data store is closed, the DataSourceChangedNotifier becomes inactive and should no longer be used, as invoking its methods will result in an IllegalStateException.

Important: This is a Public Preview API. It may be changed or removed at any time.
