Class PSVIDOMImplementationImpl

Implemented Interfaces:
DOMImplementation, DOMImplementationLS

public class PSVIDOMImplementationImpl
extends CoreDOMImplementationImpl

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 Details

createDocument

public Document createDocument(String namespaceURI,
                               String qualifiedName,
                               DocumentType doctype)
            throws DOMException
Introduced in DOM Level 2.

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

Overrides:
createDocument in interface CoreDOMImplementationImpl
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:
Document A new Document object.

getDOMImplementation

public static DOMImplementation getDOMImplementation()
NON-DOM: Obtain and return the single shared object
Overrides:
getDOMImplementation in interface CoreDOMImplementationImpl

hasFeature

public boolean hasFeature(String feature,
                          String version)
Test if the DOM implementation supports a specific "feature" -- currently meaning language and level thereof.
Overrides:
hasFeature in interface CoreDOMImplementationImpl
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"
Returns:
true iff this implementation is compatable with the specified feature and version.
