Interface DOMImplementation
- All Known Subinterfaces:
- HTMLDOMImplementation
- 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.
Method Summary |
Document |
createDocument(java.lang.String namespaceURI,
java.lang.String qualifiedName,
DocumentType doctype)
Creates an XML Document object of the specified type with
its document element. |
DocumentType |
createDocumentType(java.lang.String qualifiedName,
java.lang.String publicId,
java.lang.String systemId,
java.lang.String internalSubset)
Creates an empty DocumentType node. |
boolean |
hasFeature(java.lang.String feature,
java.lang.String version)
Test if the DOM implementation implements a specific feature. |
hasFeature
public boolean hasFeature(java.lang.String feature,
java.lang.String version)
- Test if the DOM implementation implements a specific feature.
- Parameters:
feature
- The string of the feature to test (case-insensitive). The
legal values are defined throughout this specification. The string
must be an XML name (see also ).version
- This is the version number of the feature to test. In
Level 2, this is the string "2.0". If the version is not specified,
supporting any version of the feature will cause the method to
return true
.- Returns:
true
if the feature is implemented in the
specified version, false
otherwise.
createDocumentType
public DocumentType createDocumentType(java.lang.String qualifiedName,
java.lang.String publicId,
java.lang.String systemId,
java.lang.String internalSubset)
- 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.
- Parameters:
qualifiedName
- The qualified name of the document type to be
created.publicId
- The external subset public identifier.systemId
- The external subset system identifier.internalSubset
- The internal subset as a string. This should be
valid.- Returns:
- A new
DocumentType
node with
Node.ownerDocument
set to null
. - Since:
- DOM Level 2
createDocument
public Document createDocument(java.lang.String namespaceURI,
java.lang.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.
- Parameters:
namespaceURI
- The namespace URI of the document element to
create, or null
.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 - WRONG_DOCUMENT_ERR: Raised if
doctype
has already been
used with a different document. - Since:
- DOM Level 2
