public interface DOMImplementation
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 3 Core Specification.
| Modifier and Type | Method and Description |
|---|---|
Document |
createDocument(String
Creates a DOM Document object of the specified type with its document element.
|
DocumentType |
createDocumentType(String
Creates an empty
DocumentType node.
|
Object |
getFeature(String
This method returns a specialized object which implements the specialized APIs of the specified feature and version, as specified in
DOM Features.
|
boolean |
hasFeature(String
Test if the DOM implementation implements a specific feature and version, as specified in
DOM Features.
|
boolean hasFeature(Stringfeature, String version)
feature - The name of the feature to test.
version - This is the version number of the feature to test.
true if the feature is implemented in the specified version,
false otherwise.
DocumentTypecreateDocumentType(String qualifiedName, String publicId, String systemId) throws DOMException
DocumentType node. Entity declarations and notations are not made available. Entity reference expansions and default attribute additions do not occur..
qualifiedName - The qualified name of the document type to be created.
publicId - The external subset public identifier.
systemId - The external subset system identifier.
DocumentType node with
Node.ownerDocument set to
null.
DOMException - INVALID_CHARACTER_ERR: Raised if the specified qualified name is not an XML name according to [
XML 1.0].
qualifiedName is malformed.
DocumentcreateDocument(String namespaceURI, String qualifiedName, DocumentType doctype) throws DOMException
DocumentType given to create the document, the implementation may instantiate specialized
Document objects that support additional features than the "Core", such as "HTML" [
DOM Level 2 HTML] . On the other hand, setting the
DocumentType after the document was created makes this very unlikely to happen. Alternatively, specialized
Document creation methods, such as
createHTMLDocument [
DOM Level 2 HTML] , can be used to obtain specific types of
Document objects.
namespaceURI - The namespace URI of the document element to create or
null.
qualifiedName - The qualified name of the document element to be created or
null.
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.
Document object with its document element. If the
NamespaceURI,
qualifiedName, and
doctype are
null, the returned
Document is empty with no document element.
DOMException - INVALID_CHARACTER_ERR: Raised if the specified qualified name is not an XML name according to [
XML 1.0].
qualifiedName is malformed, if the
qualifiedName has a prefix and the
namespaceURI is
null, or if the
qualifiedName is
null and the
namespaceURI is different from
null, or if the
qualifiedName has a prefix that is "xml" and the
namespaceURI is different from "
http://www.w3.org/XML/1998/namespace" [
XML Namespaces] , 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.
doctype has already been used with a different document or was created from a different implementation.
ObjectgetFeature(String feature, String version)
DOMImplementation interface.
feature - The name of the feature requested. Note that any plus sign "+" prepended to the name of the feature will be ignored since it is not significant in the context of this method.
version - This is the version number of the feature to test.
null if there is no object which implements interfaces associated with that feature. If the
DOMObject returned by this method implements the
DOMImplementation interface, it must delegate to the primary core
DOMImplementation and not return results inconsistent with the primary core
DOMImplementation such as
hasFeature,
getFeature, etc.
