Rake::LinkedList::EmptyLinkedList

v2_1_10 - Show latest stable - Superclass: Rake::LinkedList

Represent an empty list, using the Null Object Pattern.

When inheriting from the LinkedList class, you should implement a type specific Empty class as well. Make sure you set the class instance variable @parent to the assocated list class (this allows conj, cons and make to work polymorphically).
