Class DomImpl
- DOMImplementation, DOMImplementationLS
public class DomImpl
extends java.lang.Object
"DOMImplementation" implementation.
At this writing, the following features are supported:
"XML" (L1, L2, L3),
"Events" (L2), "MutationEvents" (L2), "USER-Events" (a conformant extension),
"HTMLEvents" (L2), "UIEvents" (L2), "Traversal" (L2), "XPath" (L3),
"LS" (L3) "LS-Async" (L3).
It is possible to compile the package so it doesn't support some of these
features (notably, Traversal).
DomImpl() - Constructs a DOMImplementation object which supports
"XML" and other DOM Level 2 features.
|

LSInput.characterStream , LSInput.byteStream

LSInput.publicId , LSInput.baseURI , and
LSInput.encoding are null, and
LSInput.certifiedText is false.
|
LSOutput | createLSOutput() - Create a new empty output destination object where
LSOutput.characterStream ,
LSOutput.byteStream , LSOutput.systemId ,
LSOutput.encoding are null.

LSParser | createLSParser(short mode, String schemaType) - Create a new
LSParser .

LSSerializer | createLSSerializer() - Create a new
LSSerializer object.
|
Object | getFeature(String feature, String version) - This method returns a specialized object which implements the
specialized APIs of the specified feature and version, as specified
in .
|
boolean | hasFeature(String name, String version) - DOM L1
Returns true if the specified feature and version are
supported.

DomImpl
public DomImpl()
Constructs a DOMImplementation object which supports
"XML" and other DOM Level 2 features.
createDocument
public Document createDocument(String namespaceURI,
String rootName,
DocumentType doctype)
DOM L2
Creates and returns a Document, populated only with a root element and
optionally a document type(if that was provided).
- createDocument in interface DOMImplementation
createDocumentType
public DocumentType createDocumentType(String rootName,
String publicId,
String systemId)
DOM L2
Creates and returns a DocumentType, associated with this
implementation. This DocumentType can have no associated
objects(notations, entities) until the DocumentType is
first associated with a document.
Note that there is no implication that this DTD will
be parsed by the DOM, or ever have contents. Moreover, the
DocumentType created here can only be added to a document by
the createDocument method(below).
That means that the only
portable way to create a Document object is to start parsing,
queue comment and processing instruction (PI) nodes, and then only
create a DOM Document after (a) it's known if a DocumentType
object is needed, and (b) the name and namespace of the root
element is known. Queued comment and PI nodes would then be
inserted appropriately in the document prologue, both before and
after the DTD node, and additional attributes assigned to the
root element.
(One hopes that the final DOM REC fixes this serious botch.)
- createDocumentType in interface DOMImplementation
createLSInput
public LSInput createLSInput()
Create a new empty input source object where
LSInput.characterStream
, LSInput.byteStream
, LSInput.stringData
LSInput.systemId
,
LSInput.publicId
, LSInput.baseURI
, and
LSInput.encoding
are null, and
LSInput.certifiedText
is false.
- createLSInput in interface DOMImplementationLS
- The newly created input object.
createLSOutput
public LSOutput createLSOutput()
Create a new empty output destination object where
LSOutput.characterStream
,
LSOutput.byteStream
, LSOutput.systemId
,
LSOutput.encoding
are null.
- createLSOutput in interface DOMImplementationLS
- The newly created output object.
createLSParser
public LSParser createLSParser(short mode,
String schemaType)
throws DOMException
Create a new LSParser
. The newly constructed parser may
then be configured by means of its DOMConfiguration
object, and used to parse documents by means of its parse
method.
- createLSParser in interface DOMImplementationLS
mode
- The mode
argument is either
MODE_SYNCHRONOUS
or MODE_ASYNCHRONOUS
, if
mode
is MODE_SYNCHRONOUS
then the
LSParser
that is created will operate in synchronous
mode, if it's MODE_ASYNCHRONOUS
then the
LSParser
that is created will operate in asynchronous
mode.schemaType
- An absolute URI representing the type of the schema
language used during the load of a Document
using the
newly created LSParser
. Note that no lexical checking
is done on the absolute URI. In order to create a
LSParser
for any kind of schema types (i.e. the
LSParser will be free to use any schema found), use the value
null
.
Note: For W3C XML Schema [XML Schema Part 1]
, applications must use the value
"http://www.w3.org/2001/XMLSchema"
. For XML DTD [XML 1.0],
applications must use the value
"http://www.w3.org/TR/REC-xml"
. Other Schema languages
are outside the scope of the W3C and therefore should recommend an
absolute URI in order to use this method.
- The newly created
LSParser
object. This
LSParser
is either synchronous or asynchronous
depending on the value of the mode
argument.
Note: By default, the newly created LSParser
does not contain a DOMErrorHandler
, i.e. the value of
the "
error-handler" configuration parameter is null
. However, implementations
may provide a default error handler at creation time. In that case,
the initial value of the "error-handler"
configuration
parameter on the new LSParser
object contains a
reference to the default error handler.
DOMException
- NOT_SUPPORTED_ERR: Raised if the requested mode or schema type is
not supported.
createLSSerializer
public LSSerializer createLSSerializer()
Create a new LSSerializer
object.
- createLSSerializer in interface DOMImplementationLS
- The newly created
LSSerializer
object.
Note: By default, the newly created
LSSerializer
has no DOMErrorHandler
, i.e.
the value of the "error-handler"
configuration
parameter is null
. However, implementations may
provide a default error handler at creation time. In that case, the
initial value of the "error-handler"
configuration
parameter on the new LSSerializer
object contains a
reference to the default error handler.
getFeature
public Object getFeature(String feature,
String version)
This method returns a specialized object which implements the
specialized APIs of the specified feature and version, as specified
in . The specialized object may also be obtained by using
binding-specific casting methods but is not necessarily expected to,
as discussed in . This method also allow the implementation to
provide specialized objects which do not support the
DOMImplementation
interface.
- getFeature in interface DOMImplementation
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.
- Returns an object which implements the specialized APIs of
the specified feature and version, if any, or
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.
- DOM Level 3
hasFeature
public boolean hasFeature(String name,
String version)
DOM L1
Returns true if the specified feature and version are
supported. Note that the case of the feature name is ignored.
