Interface DOMImplementation


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 a DOM 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.

Parameters:
feature - The name of the feature to test (case-insensitive). The values used by DOM features are defined throughout the DOM Level 2 specifications and listed in the section. The name must be an XML name. To avoid possible conflicts, as a convention, names referring to features defined outside the DOM specification should be made unique.
version - This is the version number of the feature to test. In Level 2, the string can be either "2.0" or "1.0". If the version is not specified, supporting any version of the feature causes the method to return true.
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.

Parameters:
qualifiedName - The qualified name of the document type to be created.
publicId - The external subset public identifier.
systemId - The external subset system identifier.
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.
NOT_SUPPORTED_ERR: May be raised by DOM implementations which do not support the "XML" feature, if they choose not to support this method. Other features introduced in the future, by the DOM WG or in extensions defined by other groups, may also demand support for this method; please consult the definition of the feature to see if it requires this method.
Since:
DOM Level 2

createDocument

public Document createDocument(String namespaceURI,
                               String qualifiedName,
                               DocumentType doctype)
                        throws DOMException
Creates a DOM Document object of the specified type with its document element.

Parameters:
namespaceURI - The namespace URI of the document element to create.
qualifiedName - The qualified name of the document element to be created.
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:
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" , or if the DOM implementation does not support the "XML" feature but a non-null namespace URI was provided, since namespaces were defined by XML.
WRONG_DOCUMENT_ERR: Raised if doctype has already been used with a different document or was created from a different implementation.
NOT_SUPPORTED_ERR: May be raised by DOM implementations which do not support the "XML" feature, if they choose not to support this method. Other features introduced in the future, by the DOM WG or in extensions defined by other groups, may also demand support for this method; please consult the definition of the feature to see if it requires this method.
Since:
DOM Level 2
