All Implemented Interfaces:

IlvDocument, IlvFileDocument, IlvStreamDocument, ActionHandler, MessageListener, IlvPropertyManager, ActionListener, EventListener

public class IlvDOMDocument
extends IlvAbstractFileDocument

Defines documents that are associated with org.w3c.dom.Document instances. If an IlvDOMDocument is initialized with the initializeDocument(java.lang.Object) method, an empty org.w3c.dom.Document is created and associated with the document.
If an IlvDOMDocument is initialized from a file URL with the method readDocument(java.net.URL, ilog.views.appframe.docview.IlvFileFilter), the specified file is considered as an XML file and its content is parsed into the associated org.w3c.dom.Document instance of the document.

The DOM document associated with an IlvDOMDocument is accessed with the method getDOMDocument().
