public class DOMImplementationImpl

extends java.lang.Object

implements DOMImplementation

The DOMImplementation class is description of a particular implementation of the Document Object Model. As such its data is static, shared by all instances of this implementation.

The DOM API requires that it be a real object rather than static methods. However, there's nothing that says it can't be a singleton, so that's how I've implemented it.

Method Detail

hasFeature

public boolean hasFeature(java.lang.String feature,
                          java.lang.String version)

Test if the DOM implementation supports a specific "feature" -- currently meaning language and level thereof.

Specified by:

hasFeature in interface DOMImplementation

Parameters:

feature - The package name of the feature to test. In Level 1, supported values are "HTML" and "XML" (case-insensitive). At this writing, org.apache.xerces.dom supports only XML.

version - The version number of the feature being tested. This is interpreted as "Version of the DOM API supported for the specified Feature", and in Level 1 should be "1.0"

getDOMImplementation

public static DOMImplementation getDOMImplementation()

NON-DOM: Obtain and return the single shared object

createDocumentType

public DocumentType createDocumentType(java.lang.String qualifiedName,
                                       java.lang.String publicID,
                                       java.lang.String systemID)

Introduced in DOM Level 2.

Creates an empty DocumentType node.

Specified by:

public Document createDocument(java.lang.String namespaceURI,
                               java.lang.String qualifiedName,
                               DocumentType doctype)
                        throws DOMException

Introduced in DOM Level 2.

Creates an XML Document object of the specified type with its document element.

Specified by:

createDocument in interface DOMImplementation

Parameters:

namespaceURI - The namespace URI of the document element to create, or null.

qualifiedName - The qualified name of the document element to create.

doctype - The type of document to be created or null.

When doctype is not null, its Node.ownerDocument attribute is set to the document being created.

Returns:
