# BSON::MaxKey - phpMan

## NAME
    [BSON::MaxKey] - BSON type wrapper for MaxKey

## VERSION
    version v1.12.2

## 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://github.com/mongodb/specifications/blob/master/source/extended-j>
    son.rst> 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.
