Detailed Description

Class ilLMPageObject.

Handles Page Objects of ILIAS Learning Modules

Note: This class has a member variable that contains an instance of class ilPageObject 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 learning modules or glossaries definitions. This class, ilLMPageObject, provides additional methods for the handling of page objects in learning modules.
