Class ImmutableNode

java.lang.Object

uk.ac.cam.acr31.life.hash.Node

uk.ac.cam.acr31.life.hash.ImmutableNode

Direct Known Subclasses:

WorkerNode

abstract class ImmutableNode
extends Node

Partial implementation of the Node interface. Uses private, final member fields to enforce immutability. This class deals with data storage of members and accessors. Manipulation functions are left unimplemented. We override the hashCode and equals methods so that two ImmutableNodes with the equal child ImmutableNodes are equal.
