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(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)
Creates an empty DocumentType node. |
boolean |
hasFeature(java.lang.String feature,
java.lang.String version)
Test if the DOM implementation implements a specific feature. |
Method Detail |
public boolean hasFeature(java.lang.String feature, java.lang.String version)
featureThe
- 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 by reversing the name of the Internet domain name of the
person (or the organization that the person belongs to) who defines
the feature, component by component, and using this as a prefix.
For instance, the W3C SVG Working Group defines the feature
"org.w3c.dom.svg".versionThis
- 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
.true
if the feature is implemented in the
specified version, false
otherwise.public DocumentType createDocumentType(java.lang.String qualifiedName, java.lang.String publicId, java.lang.String systemId) throws DOMException
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
.
qualifiedNameThe
- qualified name of the document type to be
created.publicIdThe
- external subset public identifier.systemIdThe
- external subset system identifier.DocumentType
node with
Node.ownerDocument
set to null
.DOMException
- INVALID_CHARACTER_ERR: Raised if the specified qualified name
contains an illegal character.
qualifiedName
is
malformed.public Document createDocument(java.lang.String namespaceURI, java.lang.String qualifiedName, DocumentType doctype) throws DOMException
Document
object of the specified type with
its document element. HTML-only DOM implementations do not need to
implement this method.namespaceURIThe
- namespace URI of the document element to create.qualifiedNameThe
- qualified name of the document element to be
created.doctypeThe
- 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.DOMException
- INVALID_CHARACTER_ERR: Raised if the specified qualified name
contains an illegal character.
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" .
doctype
has already
been used with a different document or was created from a different
implementation.
