StaticInstanceInterface is the interface for providing static instances to classes, which can be used to obtain class meta information that can not be expressed in static methods.

For example: adjustments made by DI or behaviors reveal only at object level, but might be needed at class (static) level as well.

To implement the instance() method you may use yii\base\StaticInstanceTrait.
