Interface DOMImplementation

All Known Implementing Classes:

DOMImplementationImpl

public interface DOMImplementation

The DOMImplementation interface provides a number of methods for performing operations that are independent of any particular instance of the document object model.

See also the Document Object Model (DOM) Level 2 Core Specification.

Method Summary

Document	createDocument(String namespaceURI, String qualifiedName, DocumentType doctype) Creates an XML Document object of the specified type with its document element.
DocumentType	createDocumentType(String qualifiedName, String publicId, String systemId) Creates an empty DocumentType node.
boolean	hasFeature(String feature, String version) Test if the DOM implementation implements a specific feature.

Method Detail

hasFeature

public boolean hasFeature(String feature,
                          String version)

Test if the DOM implementation implements a specific feature.

Returns:

true if the feature is implemented in the specified version, false otherwise.

createDocumentType

public DocumentType createDocumentType(String qualifiedName,
                                       String publicId,
                                       String systemId)
                                throws DOMException

Creates an empty DocumentType node. Entity declarations and notations are not made available. Entity reference expansions and default attribute additions do not occur. It is expected that a future version of the DOM will provide a way for populating a DocumentType.
HTML-only DOM implementations do not need to implement this method.

Returns:

A new DocumentType node with Node.ownerDocument set to null.

Throws:

DOMException - INVALID_CHARACTER_ERR: Raised if the specified qualified name contains an illegal character.
NAMESPACE_ERR: Raised if the qualifiedName is malformed.

Since:

DOM Level 2

createDocument

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

Creates an XML Document object of the specified type with its document element. HTML-only DOM implementations do not need to implement this method.

Returns:

A new Document object.

Throws:

DOMException - INVALID_CHARACTER_ERR: Raised if the specified qualified name contains an illegal character.
NAMESPACE_ERR: Raised if the qualifiedName is malformed, if the qualifiedName has a prefix and the namespaceURI is null, or if the qualifiedName has a prefix that is "xml" and the namespaceURI is different from " http://www.w3.org/XML/1998/namespace" .
WRONG_DOCUMENT_ERR: Raised if doctype has already been used with a different document or was created from a different implementation.

Since:

DOM Level 2
