public interface DataListener
The DataListener
is used to receive notifications about data availability
in the corresponding data providers.
Generally, the notification is issued only if provider transforms from 'empty' state into 'available' state at some moment after transition. In other cases notification is not issued, though certain exclusions exist. The notification is issued in a state that allows listener to perform potentially costly operations like event scheduling, synchronization, or farther notification.
