  Details                        
    buildForm(FormBuilderInterface $builder, array $options)
          Builds the form. This method is called for each type in the hierarchy starting from the top most type. Type extensions can further modify the form. Parameters   FormBuilderInterface $builder The form builder   array $options The options                         
    buildView(FormView $view, FormInterface $form, array $options)
          Builds the form view. This method is called for each type in the hierarchy starting from the top most type. Type extensions can further modify the view. A view of a form is built before the views of the child forms are built. This means that you cannot access child views in this method. If you need to do so, move your logic to {@link finishView()} instead. Parameters   FormView $view The view   FormInterface $form The form   array $options The options                         
    finishView(FormView $view, FormInterface $form, array $options)
          Finishes the form view. This method gets called for each type in the hierarchy starting from the top most type. Type extensions can further modify the view. When this method is called, views of the form's children have already been built and finished and can be accessed. You should only implement such logic in this method that actually accesses child views. For everything else you are recommended to implement {@link buildView()} instead. Parameters   FormView $view The view   FormInterface $form The form   array $options The options                         
    configureOptions(OptionsResolver $resolver)
          Configures the options for this type. Parameters   OptionsResolver $resolver The resolver for the options                         string
    getBlockPrefix()
          Returns the prefix of the template block name for this type. The block prefix defaults to the underscored short class name with the "Type" suffix removed (e.g. "UserProfileType" => "user_profile"). Return Value   string The prefix of the template block name                         string|null
    getParent()
          Returns the name of the parent type. Return Value   string|null The name of the parent type if any, null otherwise    ChoiceListInterface
    loadChoiceList(null|callable $value = null)
          Loads a list of choices. Optionally, a callable can be passed for generating the choice values. The callable receives the choice as first and the array key as the second argument. Parameters   null|callable $value The callable which generates the values from choices   Return Value   ChoiceListInterface The loaded choice list                         array
    loadChoicesForValues(array $values, null|callable $value = null)
          Loads the choices corresponding to the given values. The choices are returned with the same keys and in the same order as the corresponding values in the given array. Optionally, a callable can be passed for generating the choice values. The callable receives the choice as first and the array key as the second argument. Parameters   array $values An array of choice values. Non-existing values in this array are ignored   null|callable $value The callable generating the choice values   Return Value   array An array of choices                         string[]
    loadValuesForChoices(array $choices, null|callable $value = null)
          Loads the values corresponding to the given choices. The values are returned with the same keys and in the same order as the corresponding choices in the given array. Optionally, a callable can be passed for generating the choice values. The callable receives the choice as first and the array key as the second argument. Parameters   array $choices An array of choices. Non-existing choices in this array are ignored   null|callable $value The callable generating the choice values   Return Value   string[] An array of choice values
