org.opencms.ade.sitemap.CmsSitemapNavPosCalculator

public class CmsSitemapNavPosCalculator
extends Object

Helper class for recalculating navigation positions when a user has changed the order of navigation entries in the sitemap editor.

This is harder than it sounds because we need to handle special cases like e.g. the user inserting an entry between two existing entries with the same navigation position, which means we need to update the navigation positions of multiple entries to force the ordering which the user wanted.
