- * @workInProgress
- * @ngdoc formatter
- * @name angular.formatter.index
- * @deprecated
- * @description
- * Index formatter is meant to be used with `select` input widget. It is useful when one needs
- * to select from a set of objects. To create pull-down one can iterate over the array of object
- * to build the UI. However  the value of the pull-down must be a string. This means that when on
- * object is selected form the pull-down, the pull-down value is a string which needs to be
- * converted back to an object. This conversion from string to on object is not possible, at best
- * the converted object is a copy of the original object. To solve this issue we create a pull-down
- * where the value strings are an index of the object in the array. When pull-down is selected the
- * index can be used to look up the original user object.
- *
- * @inputType select
- * @param {array} array to be used for selecting an object.
- * @returns {object} object which is located at the selected position.
