As we can see from the interface shown in full below, this is not a small interface.

This isn’t actually as scary as it looks. No, really, I mean that. Many of the methods (the ones that we didn’t show in the smaller version) register and unregister listeners for various types of events related to tables in the SI database. These allow applications to be notified whenever a specific set of information in an SI table changes.
Similarly, although most of the methods for retrieving information look very complex, the first three parameters are always the same. These are described in the main page.
