Class DomImpl

Implemented Interfaces:
DOMImplementation, org.w3c.dom.ls.DOMImplementationLS

public class DomImpl
extends java.lang.Object
implements DOMImplementation, org.w3c.dom.ls.DOMImplementationLS

"DOMImplementation" implementation.

At this writing, the following features are supported: "XML" (L1, L2, L3), "Events" (L2), "MutationEvents" (L2), "USER-Events" (a conformant extension), "HTMLEvents" (L2), "UIEvents" (L2), "Traversal" (L2), "XPath" (L3), "LS" (L3) "LS-Async" (L3). It is possible to compile the package so it doesn't support some of these features (notably, Traversal).

Method Details

createDocument

public Document createDocument(String namespaceURI,
                               String rootName,
                               DocumentType doctype)
DOM L2 Creates and returns a Document, populated only with a root element and optionally a document type(if that was provided).
Specified by:
createDocument in interface DOMImplementation


createDocumentType

public DocumentType createDocumentType(String rootName,
                                       String publicId,
                                       String systemId)
DOM L2 Creates and returns a DocumentType, associated with this implementation. This DocumentType can have no associated objects(notations, entities) until the DocumentType is first associated with a document.

Note that there is no implication that this DTD will be parsed by the DOM, or ever have contents. Moreover, the DocumentType created here can only be added to a document by the createDocument method(below). That means that the only portable way to create a Document object is to start parsing, queue comment and processing instruction (PI) nodes, and then only create a DOM Document after (a) it's known if a DocumentType object is needed, and (b) the name and namespace of the root element is known. Queued comment and PI nodes would then be inserted appropriately in the document prologue, both before and after the DTD node, and additional attributes assigned to the root element. (One hopes that the final DOM REC fixes this serious botch.)
