|
|
* This class provides an easy way for apps to store config values in the
|
|
* database.
|
|
*
|
|
* **Note:** since 29.0.0, it supports **lazy loading**
|
|
*
|
|
* ### What is lazy loading ?
|
|
* In order to avoid loading useless config values into memory for each request,
|
|
* only non-lazy values are now loaded.
|
|
*
|
|
* Once a value that is lazy is requested, all lazy values will be loaded.
|
|
*
|
|
* Similarly, some methods from this class are marked with a warning about ignoring
|
|
* lazy loading. Use them wisely and only on parts of the code that are called
|
|
* during specific requests or actions to avoid loading the lazy values all the time.
|
|
*

* @since 7.0.0
