public interface ISourceProvider
A provider of notifications for when a change has occurred to a particular type of source. These providers can be given to the appropriate service, and this service will then re-evaluate the appropriate pieces of its internal state in response to these changes.
It is recommended that clients subclass AbstractSourceProvider
instead, as this provides some common support for listeners.
