/**
 * Extends the base Query class to provide new methods related to association
 * loading, automatic fields selection, automatic type casting and to wrap results
 * into a specific iterator that will be responsible for hydrating results if
 * required.
 *
 * @see \Cake\Collection\CollectionInterface For a full description of the collection methods supported by this class
 * @method \Cake\Collection\CollectionInterface each(callable $c) Passes each of the query results to the callable
 * @method \Cake\Collection\CollectionInterface filter(callable $c = null) Keeps the results using passing the callable test
 * @method \Cake\Collection\CollectionInterface reject(callable $c) Removes the results passing the callable test
 * @method bool every(callable $c) Returns true if all the results pass the callable test
 * @method bool some(callable $c) Returns true if at least one of the results pass the callable test
 * @method \Cake\Collection\CollectionInterface map(callable $c) Modifies each of the results using the callable
 * @method mixed reduce(callable $c, $zero = null) Folds all the results into a single value using the callable.
 * @method \Cake\Collection\CollectionInterface extract($field) Extracts a single column from each row
 * @method mixed max($field, $type = SORT_NUMERIC) Returns the maximum value for a single column in all the results.
 * @method mixed min($field, $type = SORT_NUMERIC) Returns the minimum value for a single column in all the results.
 * @method \Cake\Collection\CollectionInterface groupBy(string|callable $field) In-memory group all results by the value of a column.
 * @method \Cake\Collection\CollectionInterface indexBy(string|callable $field) Returns the results indexed by the value of a column.

 * @method float sumOf(string|callable $field) Returns the sum of all values for a single column
 * @method \Cake\Collection\CollectionInterface shuffle() In-memory randomize the order the results are returned
 * @method \Cake\Collection\CollectionInterface sample($size = 10) In-memory shuffle the results and return a subset of them.
 * @method \Cake\Collection\CollectionInterface take($size = 1, $from = 0) In-memory limit and offset for the query results.

 * @method \Cake\Collection\CollectionInterface append(array|\Traversable $items) Appends more rows to the result of the query.
 * @method \Cake\Collection\CollectionInterface combine($k, $v, $g = null) Returns the values of the column $v index by column $k,
 *   and grouped by $g.
 * @method \Cake\Collection\CollectionInterface nest($k, $p, $n = 'children') Creates a tree structure by nesting the values of column $p into that
 *   with the same value for $k using $n as the nesting key.
 * @method array toArray() Returns a key-value array with the results of this query.
 * @method array toList() Returns a numerically indexed array with the results of this query.
 * @method \Cake\Collection\CollectionInterface stopWhen(callable $c) Returns each row until the callable returns true.
 * @method \Cake\Collection\CollectionInterface zip(array|\Traversable $c) Returns the first result of both the query and $c in an array,
 *   then the second results and so on.
 * @method \Cake\Collection\CollectionInterface zipWith($collections, callable $callable) Returns each of the results out of calling $c

/**
     * Sets the list of associations that should be eagerly loaded along with this
     * query. The list of associated tables passed must have been previously set as
     * associations using the Table API.
     *
     * ### Example:
     *
     * ```
     * // Bring articles' author information
     * $query->contain('Author');
     *
     * // Also bring the category and tags associated to each article
     * $query->contain(['Category', 'Tag']);
     * ```
     *
     * Associations can be arbitrarily nested using dot notation or nested arrays,
     * this allows this object to calculate joins or any additional queries that
     * must be executed to bring the required associated data.
     *
     * ### Example:
     *
     * ```
     * // Eager load the product info, and for each product load other 2 associations
     * $query->contain(['Product' => ['Manufacturer', 'Distributor']);
     *
     * // Which is equivalent to calling
     * $query->contain(['Products.Manufactures', 'Products.Distributors']);
     *
     * // For an author query, load his region, state and country
     * $query->contain('Regions.States.Countries');
     * ```
     *
     * It is possible to control the conditions and fields selected for each of the
     * contained associations:
     *
     * ### Example:
     *
     * ```
     * $query->contain(['Tags' => function ($q) {
     *     return $q->where(['Tags.is_popular' => true]);
     * }]);
     *
     * $query->contain(['Products.Manufactures' => function ($q) {
     *     return $q->select(['name'])->where(['Manufactures.active' => true]);
     * }]);
     * ```
     *
     * Each association might define special options when eager loaded, the allowed
     * options that can be set per association are:
     *
     * - `foreignKey`: Used to set a different field to match both tables, if set to false
     *   no join conditions will be generated automatically. `false` can only be used on
     *   joinable associations and cannot be used with hasMany or belongsToMany associations.
     * - `fields`: An array with the fields that should be fetched from the association.
     * - `finder`: The finder to use when loading associated records. Either the name of the
     *   finder as a string, or an array to define options to pass to the finder.
     * - `queryBuilder`: Equivalent to passing a callable instead of an options array.
     *
     * ### Example:
     *
     * ```
     * // Set options for the hasMany articles that will be eagerly loaded for an author
     * $query->contain([
     *     'Articles' => [
     *         'fields' => ['title', 'author_id']
     *     ]
     * ]);
     * ```
     *
     * Finders can be configured to use options.
     *
     * ```
     * // Retrieve translations for the articles, but only those for the `en` and `es` locales
     * $query->contain([
     *     'Articles' => [
     *         'finder' => [
     *             'translations' => [
     *                 'locales' => ['en', 'es']
     *             ]
     *         ]
     *     ]
     * ]);
     * ```
     *
     * When containing associations, it is important to include foreign key columns.
     * Failing to do so will trigger exceptions.
     *
     * ```
     * // Use a query builder to add conditions to the containment
     * $query->contain('Authors', function ($q) {
     *     return $q->where(...); // add conditions
     * });
     * // Use special join conditions for multiple containments in the same method call
     * $query->contain([
     *     'Authors' => [
     *         'foreignKey' => false,
     *         'queryBuilder' => function ($q) {
     *             return $q->where(...); // Add full filtering conditions
     *         }

     *         return $q->where(...); // add conditions
     *     }
     * ]);
     * ```
