/**
 | 
						|
 * Collection represents the Mongo collection information.
 | 
						|
 *
 | 
						|
 * A collection object is usually created by calling [[Database::getCollection()]] or [[Connection::getCollection()]].
 | 
						|
 *
 | 
						|
 * Collection provides the basic interface for the Mongo queries, mostly: insert, update, delete operations.
 | 
						|
 * For example:
 | 
						|
 *
 | 
						|
 * ~~~
 | 
						|
 * $collection = Yii::$app->mongodb->getCollection('customer');
 | 
						|
 * $collection->insert(['name' => 'John Smith', 'status' => 1]);
 | 
						|
 * ~~~
 | 
						|
 *
 | 
						|
 * To perform "find" queries, please use [[Query]] instead.
 | 
						|
 *
 | 
						|
 * Mongo uses JSON format to specify query conditions with quite specific syntax.
 | 
						|
 * However Collection class provides the ability of "translating" common condition format used "yii\db\*"
 | 
						|
 * into Mongo condition.
 | 
						|
 * For example:
 | 
						|
 * ~~~
 | 
						|
 * $condition = [
 | 
						|
 *     [
 | 
						|
 *         'OR',
 | 
						|
 *         ['AND', ['first_name' => 'John'], ['last_name' => 'Smith']],
 | 
						|
 *         ['status' => [1, 2, 3]]
 | 
						|
 *     ],
 | 
						|
 * ];
 | 
						|
 * print_r($collection->buildCondition($condition));
 | 
						|
 * // outputs :
 | 
						|
 * [
 | 
						|
 *     '$or' => [
 | 
						|
 *         [
 | 
						|
 *             'first_name' => 'John',
 | 
						|
 *             'last_name' => 'John',
 | 
						|
 *         ],
 | 
						|
 *         [
 | 
						|
 *             'status' => ['$in' => [1, 2, 3]],
 | 
						|
 *         ]
 | 
						|
 *     ]
 | 
						|
 * ]
 | 
						|
 * ~~~
 | 
						|
 *
 | 
						|
 * Note: condition values for the key '_id' will be automatically cast to [[\MongoId]] instance,
 | 
						|
 * even if they are plain strings. However, if you have other columns, containing [[\MongoId]], you
 | 
						|
 * should take care of possible typecast on your own.
 | 
						|
 *
 | 
						|
 * @property string $fullName Full name of this collection, including database name. This property is
 | 
						|
 * read-only.
 | 
						|
 * @property array $lastError Last error information. This property is read-only.
 | 
						|
 * @property string $name Name of this collection. This property is read-only.
