/**
 * @file
 * Hooks provided by the Options module.
 */

/**
 * Returns the list of options to be displayed for a field.
 *
 * Field types willing to enable one or several of the widgets defined in
 * options.module (select, radios/checkboxes, on/off checkbox) need to
 * implement this hook to specify the list of options to display in the
 * widgets.
 *
 * @param $field
 *   The field definition.
 * @param $instance
 *   (optional) The instance definition. The hook might be called without an
 *   $instance parameter in contexts where no specific instance can be targeted.
 *   It is recommended to only use instance level properties to filter out
 *   values from a list defined by field level properties.
 * @param $entity_type
 *   The entity type the field is attached to.
 * @param $entity
 *   The entity object the field is attached to, or NULL if no entity
 *   exists (e.g. in field settings page).
 *
 * @return
 *   The array of options for the field. Array keys are the values to be
 *   stored, and should be of the data type (string, number...) expected by
 *   the first 'column' for the field type. Array values are the labels to
 *   display within the widgets. The labels should NOT be sanitized,
 *   options.module takes care of sanitation according to the needs of each
 *   widget. The HTML tags defined in _field_filter_xss_allowed_tags() are
 *   allowed, other tags will be filtered.
