/**

* Dynamically provide translatable entites for the {@link i18n} logic.
|
|
* This is particularly handy for natural language strings in static variables
|
|
* of a class definition, as the _t() method can only be used in a runtime/instance
|
|
* context. The provideI18nEntities() method enables you to define your own entities
|
|
* with your custom naming, mostly involving either the variable name or the array
|
|
* key. With this in place, you can use a getter method to trigger translation
|
|
* of your values.
|
|
* For any statics containing natural language, never use the static directly -
|
|
* always wrap it in a getter.
