public class DOMImplementationImpl
extends CoreDOMImplementationImpl
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.

Since:

PR-DOM-Level-1-19980818.

getDOMImplementation

public static DOMImplementation getDOMImplementation()

NON-DOM: Obtain and return the single shared object

hasFeature

public boolean hasFeature(String feature,
                          String version)

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

Specified by:

hasFeature in interface DOMImplementation

Overrides:

hasFeature in class 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.

createDocument

protected CoreDocumentImpl createDocument(DocumentType doctype)

Overrides:

createDocument in class CoreDOMImplementationImpl
