.SH DESCRIPTION
|
||
|
|
The QDomImplementation class provides information about the features of the DOM implementation.
|
||
|
|
.PP
|
||
|
|
This class describes the features that are supported by the DOM implementation. Currently the XML subset of DOM Level 1 and DOM Level 2 Core are supported.
|
||
|
|
.PP
|
||
|
|
Normally you will use the function QDomDocument::implementation() to get the implementation object.
|
||
|
|
.PP
|
||
|
|
You can create a new document type with createDocumentType() and a new document with createDocument().
|
||
|
|
.PP
|
||
|
|
For further information about the Document Object Model see http://www.w3.org/TR/REC-DOM-Level-1/ and http://www.w3.org/TR/DOM-Level-2-Core/. For a more general introduction of the DOM implementation see the QDomDocument documentation.
|
||
|
|
.PP
|
||
|
|
See also hasFeature() and XML.
|
||
|
|
.SH MEMBER FUNCTION DOCUMENTATION
|
||
|
|
.SH "QDomImplementation::QDomImplementation ()"
|
||
|
|
Constructs a QDomImplementation object.
|
||
|
|
.SH "QDomImplementation::QDomImplementation ( const QDomImplementation & x )"
|
||
|
|
Constructs a copy of \fIx\fR.
|
||
|
|
.SH "QDomImplementation::~QDomImplementation ()\fC [virtual]\fR"
|
||
|
|
Destroys the object and frees its resources.
|
||
|
|
.SH "QDomDocument QDomImplementation::createDocument ( const QString & nsURI, const QString & qName, const QDomDocumentType & doctype )\fC [virtual]\fR"
|
||
|
|
Creates a DOM document with the document type \fIdoctype\fR. This function also adds a root element node with the qualified name \fIqName\fR and the namespace URI \fInsURI\fR.
|
||
|
|
.SH "QDomDocumentType QDomImplementation::createDocumentType ( const QString & qName, const QString & publicId, const QString & systemId )\fC [virtual]\fR"
|
||
|
|
Creates a document type node for the name \fIqName\fR.
|
||
|
|
.PP
|
||
|
|
\fIpublicId\fR specifies the public identifier of the external subset. If you specify QString::null as the \fIpublicId\fR, this means that the document type has no public identifier.
|
||
|
|
.PP
|
||
|
|
\fIsystemId\fR specifies the system identifier of the external subset. If you specify QString::null as the \fIsystemId\fR, this means that the document type has no system identifier.
|
||
|
|
.PP
|
||
|
|
Since you cannot have a public identifier without a system identifier, the public identifier is set to QString::null if there is no system identifier.
|
||
|
|
.PP
|
||
|
|
DOM level 2 does not support any other document type declaration features.
|
||
|
|
.PP
|
||
|
|
The only way you can use a document type that was created this way, is in combination with the createDocument() function to create a QDomDocument with this document type.
|
||
|
|
.PP
|
||
|
|
See also createDocument().
|
||
|
|
.SH "bool QDomImplementation::hasFeature ( const QString & feature, const QString & version )\fC [virtual]\fR"
|
||
|
|
The function returns TRUE if QDom implements the requested \fIversion\fR of a \fIfeature\fR; otherwise returns FALSE.
|
||
|
|

.SH "bool QDomImplementation::isNull ()"
|
||
|
|
Returns FALSE if the object was created by QDomDocument::implementation(); otherwise returns TRUE.
|
||
|
|
.SH "bool QDomImplementation::operator!= ( const QDomImplementation & x ) const"
|
||
|
|
Returns TRUE if \fIx\fR and this DOM implementation object were created from different QDomDocuments; otherwise returns FALSE.
|
||
|
|
.SH "QDomImplementation & QDomImplementation::operator= ( const QDomImplementation & x )"
|
||
|
|
Assigns \fIx\fR to this DOM implementation.
|
||
|
|
.SH "bool QDomImplementation::operator== ( const QDomImplementation & x ) const"
|
||
|
|
Returns TRUE if \fIx\fR and this DOM implementation object were
|
||
|
|
created from the same QDomDocument; otherwise returns FALSE.
