37 * WARNING: This interface may change.
39 * This provides information about the setting - similar to the fields concept for DAO information.
40 * As the setting is serialized code creating validation setting input needs to know the data type
41 * This also helps move information out of the form layer into the data layer where people can interact with
42 * it via the API or other mechanisms. In order to keep this consistent it is important the form layer
45 * Note that this function should never be called when using the runtime getvalue function. Caching works
46 * around the expectation it will be called during setting administration
48 * Function is intended for configuration rather than runtime access to settings
50 * The following params will filter the result. If none are passed all settings will be returns
52 * @param array $filters
53 * @param int $domainID
54 * @param bool $loadOptions
57 * the following information as appropriate for each setting
