/**
 * Sort represents information relevant to sorting.
 *
 * When data needs to be sorted according to one or several attributes,
 * we can use Sort to represent the sorting information and generate
 * appropriate hyperlinks that can lead to sort actions.
 *
 * A typical usage example is as follows,
 *
 * ```php
 * public function actionIndex()
 * {
 *     $sort = new Sort([
 *         'attributes' => [
 *             'age',
 *             'name' => [
 *                 'asc' => ['first_name' => SORT_ASC, 'last_name' => SORT_ASC],
 *                 'desc' => ['first_name' => SORT_DESC, 'last_name' => SORT_DESC],
 *                 'default' => SORT_DESC,
 *                 'label' => 'Name',
 *             ],
 *         ],
 *     ]);
 *
 *     $models = Article::find()
 *         ->where(['status' => 1])
 *         ->orderBy($sort->orders)
 *         ->all();
 *
 *     return $this->render('index', [
 *          'models' => $models,
 *          'sort' => $sort,
 *     ]);
 * }
 * ```
 *
 * View:
 *
 * ```php
 * // display links leading to sort actions
 * echo $sort->link('name') . ' | ' . $sort->link('age');
 *
 * foreach ($models as $model) {
 *     // display $model here
 * }
 * ```
 *
 * In the above, we declare two [[attributes]] that support sorting: `name` and `age`.
 * We pass the sort information to the Article query so that the query results are
 * sorted by the orders specified by the Sort object. In the view, we show two hyperlinks
 * that can lead to pages with the data sorted by the corresponding attributes.
 *
 * For more details and usage information on Sort, see the [guide article on sorting](guide:output-sorting).
 *
 * @property array $attributeOrders Sort directions indexed by attribute names. Sort direction can be either
 * `SORT_ASC` for ascending order or `SORT_DESC` for descending order. Note that the type of this property
 * differs in getter and setter. See [[getAttributeOrders()]] and [[setAttributeOrders()]] for details.
 * @property-read array $orders The columns (keys) and their corresponding sort directions (values). This can
 * be passed to [[\yii\db\Query::orderBy()]] to construct a DB query.

     * @var array list of attributes that are allowed to be sorted. Its syntax can be

     * ```php
     * [
     *     'age',
     *     'name' => [
     *         'asc' => ['first_name' => SORT_ASC, 'last_name' => SORT_ASC],

     *         'label' => 'Name',
     *     ],
     * ]
     * ```
     *
     * In the above, two attributes are declared: `age` and `name`. The `age` attribute is
     * a simple attribute which is equivalent to the following:
     *
     * ```php
     * 'age' => [
     *     'asc' => ['age' => SORT_ASC],
     *     'desc' => ['age' => SORT_DESC],
     *     'default' => SORT_ASC,
     *     'label' => Inflector::camel2words('age'),
     * ]
     * ```
     *
     * Since 2.0.12 particular sort direction can be also specified as direct sort expression, like following:
     *
     * ```php
     * 'name' => [
     *     'asc' => '[[last_name]] ASC NULLS FIRST', // PostgreSQL specific feature
     *     'desc' => '[[last_name]] DESC NULLS LAST',
     * ]
     * ```
     *
     * The `name` attribute is a composite attribute:
     *
     * - The `name` key represents the attribute name which will appear in the URLs leading
     *   to sort actions.
     * - The `asc` and `desc` elements specify how to sort by the attribute in ascending
     *   and descending orders, respectively. Their values represent the actual columns and
     *   the directions by which the data should be sorted by.
     * - The `default` element specifies by which direction the attribute should be sorted
     *   if it is not currently sorted (the default value is ascending order).
     * - The `label` element specifies what label should be used when calling [[link()]] to create
     *   a sort link. If not set, [[Inflector::camel2words()]] will be called to get a label.
     *   Note that it will not be HTML-encoded.
     *
     * Note that if the Sort object is already created, you can only use the full format
     * to configure every attribute. Each attribute must include these elements: `asc` and `desc`.

18		* Sort represents information relevant to sorting.
19		*
20		* When data needs to be sorted according to one or several attributes,
21		* we can use Sort to represent the sorting information and generate
22		* appropriate hyperlinks that can lead to sort actions.
23		*
24		* A typical usage example is as follows,
25		*
26		* ```php
27		* public function actionIndex()
28		* {
29		* $sort = new Sort([
30		* 'attributes' => [
31		* 'age',
32		* 'name' => [
33		* 'asc' => ['first_name' => SORT_ASC, 'last_name' => SORT_ASC],
34		* 'desc' => ['first_name' => SORT_DESC, 'last_name' => SORT_DESC],
35		* 'default' => SORT_DESC,
36		* 'label' => 'Name',
37		* ],
38		* ],
39		* ]);
40		*
41		* $models = Article::find()
42		* ->where(['status' => 1])
43		* ->orderBy($sort->orders)
44		* ->all();
45		*
46		* return $this->render('index', [
47		* 'models' => $models,
48		* 'sort' => $sort,
49		* ]);
50		* }
51		* ```
52		*
53		* View:
54		*
55		* ```php
56		* // display links leading to sort actions
57		* echo $sort->link('name') . ' \| ' . $sort->link('age');
58		*
59		* foreach ($models as $model) {
60		* // display $model here
61		* }
62		* ```
63		*
64		* In the above, we declare two [[attributes]] that support sorting: `name` and `age`.
65		* We pass the sort information to the Article query so that the query results are
66		* sorted by the orders specified by the Sort object. In the view, we show two hyperlinks
67		* that can lead to pages with the data sorted by the corresponding attributes.
68		*
69		* For more details and usage information on Sort, see the [guide article on sorting](guide:output-sorting).
70		*
71		* @property array $attributeOrders Sort directions indexed by attribute names. Sort direction can be either
72		* `SORT_ASC` for ascending order or `SORT_DESC` for descending order. Note that the type of this property
73		* differs in getter and setter. See [[getAttributeOrders()]] and [[setAttributeOrders()]] for details.
74		* @property-read array $orders The columns (keys) and their corresponding sort directions (values). This can
75		* be passed to [[\yii\db\Query::orderBy()]] to construct a DB query.

101		* ```
102		*
103		* In the above, two attributes are declared: `age` and `name`. The `age` attribute is

107		* 'age' => [

113		* ```
114		*
115		* Since 2.0.12 particular sort direction can be also specified as direct sort expression, like following:

120		* 'desc' => '[[last_name]] DESC NULLS LAST',
121		* ]
122		* ```
123		*
124		* The `name` attribute is a composite attribute:
125		*
126		* - The `name` key represents the attribute name which will appear in the URLs leading
127		* to sort actions.
128		* - The `asc` and `desc` elements specify how to sort by the attribute in ascending
129		* and descending orders, respectively. Their values represent the actual columns and
130		* the directions by which the data should be sorted by.
131		* - The `default` element specifies by which direction the attribute should be sorted
132		* if it is not currently sorted (the default value is ascending order).
133		* - The `label` element specifies what label should be used when calling [[link()]] to create
134		* a sort link. If not set, [[Inflector::camel2words()]] will be called to get a label.
135		* Note that it will not be HTML-encoded.
136		*
