# encoding: utf-8
module Adamantium
# Module fake frozen object
#
# This behavior sometimes is needed when a mutable
# object needs to be referenced in an inmutable object tree.
#
# If you have to use `memoize :foo, freezer: :noop` to often you might
# want to include this module into your class.
#
# Use wisely! A rule of thumb only a tiny fraction of your objects
# typically deserves this.
#
module Mutable
# Noop freezer
#
# @example
# class DoesNotGetFrozen
# include Adamantium::Mutable
# end
#
# instance = DoesNotGetFrozen
# instance.freeze # => instance
#
# @return [self]
#
# @api public
#
def freeze
self
end
# Test if object is frozen
#
# @example
# class DoesNotGetFrozen
# include Adamantium::Mutable
# end
#
# instance = DoesNotGetFrozen
# instance.frozen? # => true
#
# @return [true]
#
# @api public
#
def frozen?
true

end # Mutable
