/**
 * Elements represent most of the "markup" and structure of the
 * document.  They contain both the data for the element itself
 * (element name and attributes), and any contained nodes, including
 * document text (as children).
 * 

* Elements may have Attributes associated with them; the API for this is * defined in Node, but the function is implemented here. In general, XML * applications should retrive Attributes as Nodes, since they may contain * entity references and hence be a fairly complex sub-tree. HTML users will * be dealing with simple string values, and convenience methods are provided * to work in terms of Strings. *

* DeferredElementImpl inherits from ElementImpl which does not support * Namespaces. DeferredElementNSImpl, which inherits from ElementNSImpl, does. * @see DeferredElementNSImpl * * @xerces.internal * * @version $Id: DeferredElementImpl.java 447266 2006-09-18 05:57:49Z mrglavas $ * @since PR-DOM-Level-1-19980818. */ public class DeferredElementImpl extends ElementImpl implements DeferredNode { // // Constants // /** Serialization version. */ static final long serialVersionUID = -7670981133940934842L; // // Data // /** Node index. */ protected transient int fNodeIndex; // // Constructors // /** * This is the deferred constructor.
