Overview

Null object for an empty chain.

.cons, .new

.cons	Cons a new head onto the tail list.
.empty	The standard empty list class for the given ::Rake::LinkedList class.
.make	Make a list out of the given arguments.
.new

#empty?

#empty?	Is the list empty? `.make` guards against a list being empty making any instantiated ::Rake::LinkedList object not empty by default You should consider overriding this method if you implement your own `.make` method.
#head, #tail

#==	Lists are structurally equivalent.
#conj	Polymorphically add a new element to the head of a list.
#each	For each item in the list.
#inspect	Same as #to_s, but with inspected items.
#to_s	Convert to string: LL(item, item…).

This class inherits a constructor from Rake::LinkedList::EmptyLinkedList
