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.

### PSVIDOMImplementationImpl

    public PSVIDOMImplementationImpl()

Method Detail

### getDOMImplementation

    public static org.w3c.dom.DOMImplementation getDOMImplementation()

  NON-DOM: Obtain and return the single shared object

### 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.
  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

    public org.w3c.dom.Document createDocument(java.lang.String namespaceURI,
                                               java.lang.String qualifiedName,
                                               org.w3c.dom.DocumentType doctype)
                                        throws org.w3c.dom.DOMException

  Introduced in DOM Level 2.

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

  Overrides:
    `createDocument` in class `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.
  Throws:
    `org.w3c.dom.DOMException` - WRONG_DOCUMENT_ERR: Raised if doctype has already been used with a different document.
