implements IProvider
extends java.lang.Object
implements IProvider

The abstract parent of all service providers. Implements basic support for thread-safe provider change notification.

Service implementers are expected to expose service specific provider classes extending this class.

Service provider implementers never need to extend this class directly, they instead derive their provider implementation from the service specific provider class extending this interface.
