Class ContentNavigationStep

java.lang.Object
  info.aduna.gee.spectacle.gee.NavigationStep
      info.aduna.gee.spectacle.gee.ContentNavigationStep

public class ContentNavigationStep
extends NavigationStep

A ContentNavigationStep corresponds to an option for a user to enforce a classification restriction to the current set.

For example, in a set of travel destinations to different countries, the ContentNavigationStep for the classification "Belgium" represents an option for the user to restrict the current set of destinations to only those in Belgium.

The ContentNavigationStep does not use the original classification (e.g. the String "Belgium") to which it corresponds, but instead it uses a "label". A label is just the generic, unique, opaque representation of a classification.
