15 | * Class SettingsBag | |
16 | * @package Civi\Core | |
17 | * | |
18 | * Read and write settings for a given domain (or contact). | |
19 | * | |
20 | * If the target entity does not already have a value for the setting, then | |
21 | * the defaults will be used. If mandatory values are provided, they will | |
22 | * override any defaults or custom settings. | |
23 | * | |
24 | * It's expected that the SettingsBag will have O(50-250) settings -- and that | |
25 | * we'll load the full bag on many page requests. Consequently, we don't | |
26 | * want the full metadata (help text and version history and HTML widgets) | |
27 | * for all 250 settings, but we do need the default values. | |
28 | * | |
29 | * This class is not usually instantiated directly. Instead, use SettingsManager | |
30 | * or Civi::settings(). | |
31 | * | |
32 | * @see \Civi::settings() | |
33 | * @see SettingsManagerTest | |
