public class JitNavigationSpecification
extends NavigationSpecification

Class JitNavigationSpecification implements a just-in-time NavigationSpecification. This means that even at the meta-meta level, things are calculated just in time. At the meta level, things were already calculated just-in-time by JitNavigationTree and JitNavigationDatabase At the domain level, things are currently not just-in-time -- you have to know all objects in advance.
