abstract class LazyChoiceList implements ChoiceListInterface
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.
array | getChoices() Returns the list of choices | |
array | getValues() Returns the values for the choices | |
array | getPreferredViews() Returns the choice views of the preferred choices as nested array with the choice groups as top-level keys. | |
array | getRemainingViews() Returns the choice views of the choices that are not preferred as nested array with the choice groups as top-level keys. | |
array | getChoicesForValues(array $values) Returns the choices corresponding to the given values. | |
array | getValuesForChoices(array $choices) Returns the values corresponding to the given choices. | |
array | getIndicesForChoices(array $choices) Returns the indices corresponding to the given choices. | |
array | getIndicesForValues(array $values) Returns the indices corresponding to the given values. |
Returns the list of choices
Returns the values for the choices
Returns the choice views of the preferred choices as nested array with the choice groups as top-level keys.
Example:
Returns the choice views of the choices that are not preferred as nested array with the choice groups as top-level keys.
Example:
Returns the choices corresponding to the given values.

Returns the indices corresponding to the given choices.
The indices must be positive integers or strings accepted by {@link FormConfigBuilder::validateName()}.
The index "placeholder" is internally reserved.
The indices must be returned with the same keys and in the same order as the corresponding choices in the given array.
