NAME
BSON::MaxKey - BSON type wrapper for MaxKey
VERSION
version v1.4.0
SYNOPSIS
use BSON::Types ':all'; bson_maxkey();
DESCRIPTION
This module provides a BSON type wrapper for the special BSON "MaxKey" type. The object returned is a singleton.
METHODS
TO_JSON If the "BSON_EXTJSON" option is true, returns a hashref compatible with MongoDB's extended JSON <https://docs.mongodb.org/manual/reference/mongodb-extended-json/> format, which represents it as a document as follows: {"$maxKey" : 1} If the "BSON_EXTJSON" option is false, an error is thrown, as this value can't otherwise be represented in JSON.
