Detailed Description

Class ilSCORM2004PageNode.

Handles Pages for SCORM 2004 Editing

Note: This class has a member variable that contains an instance of class ilPageObject (Services/COPage) and provides the method getPageObject() to access this instance. ilPageObject handles page objects and their content. Page objects can be assigned to different container like ILIAS learning modules, glossaries definitions. This class, ilSCORM2004PageNode, provides additional methods for the handling of page objects in the SCORM 2004 Editor.
