MongoDB\BSON\Undefined::jsonSerialize

Returns a representation that can be converted to JSON

説明

final public mixed MongoDB\BSON\Undefined::jsonSerialize()

パラメータ

この関数にはパラメータはありません。

戻り値

Returns data which can be serialized by json_encode to produce an extended JSON representation of the MongoDB\BSON\Undefined.

注意: The output is consistent with the MongoDB\BSON\toJSON function, which uses the driver-specific legacy extended JSON format. This does not necessarily match the » relaxed or » canonical extended JSON representations used by MongoDB\BSON\toRelaxedExtendedJSON and MongoDB\BSON\toCanonicalExtendedJSON, respectively.

エラー / 例外

  • Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
