The MongoDB\BSON\Undefined class

(mongodb >=1.4.0)

はじめに

BSON type for the "Undefined" type. This BSON type is deprecated, and this class can not be instantiated. It will be created from a BSON undefined type while converting BSON to PHP, and can also be converted back into BSON while storing documents in the database.
