Constructor Detail

def self.new(str : String) #

Instance Method Detail

def <=>(other : ObjectId) #

Description copied from module Comparable(BSON::ObjectId)

The comparison operator. Returns 0 if the two objects are equal, a negative number if this object is considered less than other, a positive number if this object is considered greter than other, or nil if the two objects are not comparable.

Subclasses define this method to provide class-specific ordering.

The comparison operator is usually used to sort values:

# Sort in a descending way:
[3, 1, 2].sort { |x, y| y <=> x } # => [3, 2, 1]

# Sort in an ascending way:
[3, 1, 2].sort { |x, y| x <=> y } # => [1, 2, 3]

def data : Bytes #

def to_canonical_extjson(builder : JSON::Builder) #

Serialize to a canonical extended json representation.

NOTE see https://github.com/mongodb/specifications/blob/master/source/extended-json.rst

def to_json(builder : JSON::Builder) #

def to_s(io : IO) : Nil #

Return a string hex representation of the ObjectId.
