class LazyChoiceList implements ChoiceListInterface
deprecated
since version 2.7, to be removed in 3.0. Use {@link \Symfony\Component\Form\ChoiceList\LazyChoiceList} instead.
A choice list that is loaded lazily.
This list loads itself as soon as any of the getters is accessed for the first time. You should implement loadChoiceList() in your child classes, which should return a ChoiceListInterface instance.
