de.innovationgate.webgate.api.WGContentNavigator

Utility object to navigate the content hierarchy. The WGContentNavigator in most methods takes a content as parameter and determines a content position in the site hierarchy relative to this content, e.g. the parent content or a sibling content. The return is always a valid and released content object of the same language (except in those cases, where something different is configured - as described below). So this object is used by the navigation elements of WebTML to quickly determine the content links to display.

If a content position does not provide a valid content as requested, the navigator searches further along the given direction (e.g. when searching parent, goes further up the hierarchy, when searching sibling, goes to the nex sibling) and tries to return a valid content from there. If the hierarchy ends in that direction without finding valid content, methods return null.

WGContentNavigator also takes into account visibility settings and automatically ignores contents that are not visible. Therefor the constructor takes a displaytype parameter, telling the navigator to behave like a (WebTML-Navigator), a sitemap or a search, so contents hidden from one of these facilities can be ignored.

            navigator.setOnlyPublished(!context.isbrowserinterface());
