Provides access to DVB service information.
General Design
Many of the methods in this package use a common design template. Asynchronous
method calls to retrieve data from the network all return an instance of the
SIRequest
class. Applications may use this to inquire about or
terminate the retrieval operation. When the retrieval operation completes, an
instance of a subclass of SIRetrievalEvent
will be sent to the
SIRetrievalListener
which the application passed in as a parameter
to the original method call to retrieve data from the network. When constructing
these events, the platform shall provide as the request parameter to the event
constructor, the same instance of the SIRequest
class as was
returned by the original method call which started the retrieval operation. This
SIRequest
instance shall be returned by the
getSource
method on such events.
