class_comment: '# * Form represents a form.

  # *

  # * To implement your own form fields, you need to have a thorough understanding

  # * of the data flow within a form. A form stores its data in three different

  # * representations:

  # *

  # *   (1) the "model" format required by the form''s object

  # *   (2) the "normalized" format for internal processing

  # *   (3) the "view" format used for display simple fields

  # *       or map children model data for compound fields

  # *

  # * A date field, for example, may store a date as "Y-m-d" string (1) in the

  # * object. To facilitate processing in the field, this value is normalized

  # * to a DateTime object (2). In the HTML representation of your form, a

  # * localized string (3) may be presented to and modified by the user, or it could
  be an array of values

  # * to be mapped to choices fields.

  # *

  # * In most cases, format (1) and format (2) will be the same. For example,

  # * a checkbox field uses a Boolean value for both internal processing and

  # * storage in the object. In these cases you need to set a view transformer

  # * to convert between formats (2) and (3). You can do this by calling

  # * addViewTransformer().

  # *

  # * In some cases though it makes sense to make format (1) configurable. To

  # * demonstrate this, let''s extend our above date field to store the value

  # * either as "Y-m-d" string or as timestamp. Internally we still want to

  # * use a DateTime object for processing. To convert the data from string/integer

  # * to DateTime you can set a model transformer by calling

  # * addModelTransformer(). The normalized data is then converted to the displayed

  # * data as described before.

  # *

  # * The conversions (1) -> (2) -> (3) use the transform methods of the transformers.

  # * The conversions (3) -> (2) -> (1) use the reverseTransform methods of the transformers.
