Setting
UBIK® caches all the local content (which exist on the device) in the devices' memory for fast access. However, as the number of objects grows, the device might become less responsive because of the large memory consumption. Therefore, a setting is provided to control how content is cached in the memory.
 | The default value for this setting is lazy loading. |
Eager loading
After users log in, all content is initialized and loaded into memory. This includes the content hierarchy, object display names, property values, etc.
Lazy loading
After users log in, only the essential content is loaded initially into memory. For now, this means everything other than the property values, which are then loaded whenever needed. For example,
- The icons of objects are to be displayed;
- Users need to look at the properties of objects;
- Documents(Thumbnails) are shown.
Comparison between eager loading and lazy loading
| Setting Name | Memory Usage | Loading Delay | Initialization Time after Login |
|---|---|---|---|
| Lazy Loading | Less | More | Less |
| Eager Loading | More | Less | More |
Technical background
- MetaClass and MetaProperty are not affected by the memory usage setting since they're practically needed all the time;
- Once an object's property values are cached under lazy loading setting, they will remain in the memory until one of the following happens:
- The memory allocated to UBIK® is running low;
- Offline preparation is finished with branch(es) downloaded.
