SimpleChoiceList deprecated
class SimpleChoiceList extends ChoiceList
deprecated
A choice list for choices of type string or integer.
Choices and their associated labels can be passed in a single array. Since choices are passed as array keys, only strings or integer choices are allowed. Choices may also be given as hierarchy of unlimited depth by creating nested arrays. The title of the sub-hierarchy can be stored in the array key pointing to the nested array.
$choiceList = new SimpleChoiceList(array(
'creditcard' => 'Credit card payment',
'cash' => 'Cash payment',
));

__construct(array|Traversable $choices, array $preferredChoices = array())
Creates a new simple choice list.
Parameters
| array|Traversable | $choices | The array of choices. Choices may also be given as hierarchy of unlimited depth. Hierarchies are created by creating nested arrays. The title of the sub-hierarchy can be stored in the array key pointing to the nested array. The topmost level of the hierarchy may also be a \Traversable. |
| array | $preferredChoices | A flat array of choices that should be presented to the user with priority. |
array getChoices()
Returns the list of choices.
Return Value
| array | The choices with their indices as keys |
array getValues()
Returns the values for the choices.
Return Value
| array | The values with the corresponding choice indices as keys |
array getPreferredViews()
Returns the choice views of the preferred choices as nested array with the choice groups as top-level keys.

Return Value
| array | A nested array containing the views with the corresponding choice indices as keys on the lowest levels and the choice group names in the keys of the higher levels |
array getRemainingViews()
Returns the choice views of the choices that are not preferred as nested array with the choice groups as top-level keys.
