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.
