as_extended_json(**options) click to toggle source

Converts this object to a representation directly serializable to Extended JSON (github.com/mongodb/specifications/blob/master/source/extended-json.rst).

@option opts [ nil | :relaxed | :legacy ] :mode Serialization mode

(default is canonical extended JSON)

@return [ Hash ] The extended json representation.

def as_extended_json(**options)
  { "$maxKey" => 1 }
end
as_json(*_args) click to toggle source

Return a representation of the object for use in application-level JSON serialization. Since BSON::MaxKey is used exclusively in BSON-related contexts, this method returns the canonical Extended JSON representation.

@return [ Hash ] The extended json representation.
