Example 1 with PortletTabIdResolver

use of org.apereo.portal.layout.PortletTabIdResolver in project uPortal by Jasig.

the class SingleTabUrlNodeSyntaxHelper method getFolderNamesForLayoutNode.

         * Implementation note:
         * While the API allows one or more folder names, this implementation will only ever return
         * a List with zero or one element.  It's not entirely clear that a List with zero members
         * was allowed by the interface definition, but this implementation will return an empty
         * list if the layoutNodeId cannot be found in the layout.
