QDomImplementation(3qt)

📦 version 3.3.8b, in fedora 43, fedora 44

💖 QDomImplementation(3qt) 💖

okay bestie, buckle up, we're reading the QDomImplementation page from the 3qt manual together and honestly? it's giving "quiet little class that runs the whole DOM show" 👑

✨ NAME ✨

QDomImplementation — literally just the info desk about what features your DOM implementation has 🌸

✨ SYNOPSIS ✨

first up, the big vibe announcement: all the functions in this class are reentrant when Qt is built with thread support 💅 (and yes, the page really does end that sentence with a stray </p>, we don't ask questions)

#include <qdom.h>

🌈 Public Members 🌈

here's the whole cast, no one gets left out:

  • QDomImplementation ()
  • QDomImplementation ( const QDomImplementation & x )
  • virtual ~QDomImplementation ()
  • QDomImplementation & operator= ( const QDomImplementation & x )
  • bool operator== ( const QDomImplementation & x ) const
  • bool operator!= ( const QDomImplementation & x ) const
  • virtual bool hasFeature ( const QString & feature, const QString & version )
  • virtual QDomDocumentType createDocumentType ( const QString & qName, const QString & publicId, const QString & systemId )
  • virtual QDomDocument createDocument ( const QString & nsURI, const QString & qName, const QDomDocumentType & doctype )
  • bool isNull ()

✨ DESCRIPTION ✨

so QDomImplementation is the class that tells you what the DOM implementation can actually do. it's the "what's supported, bestie?" class 🫶

it describes the features supported by the DOM implementation. right now, the XML subset of DOM Level 1 and DOM Level 2 Core are the ones on the guest list ✅

normally you don't build one yourself — you use QDomDocument::implementation() to get the implementation object. that's the main character move.

you can make a new document type with createDocumentType(), and a whole new document with createDocument() 🎀

wanna go deeper? the Document Object Model lore lives at http://www.w3.org/TR/REC-DOM-Level-1/ and http://www.w3.org/TR/DOM-Level-2-Core/. and for a more general introduction to the DOM implementation, go read the QDomDocument documentation 🌟

✨ MEMBER FUNCTION DOCUMENTATION ✨

🌸 QDomImplementation::QDomImplementation ()

constructs a QDomImplementation object. brand new, fresh out the box ✨

🌸 QDomImplementation::QDomImplementation ( const QDomImplementation & x )

constructs a copy of x. twin behavior, no cap 💕

🌸 QDomImplementation::~QDomImplementation () [virtual]

destroys the object and frees its resources. it's done, it's released, it's at peace 🦋

🌸 QDomDocument QDomImplementation::createDocument ( const QString & nsURI, const QString & qName, const QDomDocumentType & doctype ) [virtual]

creates a DOM document with the document type doctype. this function also adds a root element node with the qualified name qName and the namespace URI nsURI 👑

🌸 QDomDocumentType QDomImplementation::createDocumentType ( const QString & qName, const QString & publicId, const QString & systemId ) [virtual]

creates a document type node for the name qName 🌈

publicId specifies the public identifier of the external subset. if you pass QString::null as the publicId, that means the document type has no public identifier.

systemId specifies the system identifier of the external subset. if you pass QString::null as the systemId, that means the document type has no system identifier.

and here's the rule, bestie, write it down: 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 🚫

DOM level 2 does not support any other document type declaration features. that's it, that's the whole menu.

also lowkey important: 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.

see also createDocument() 💜

🌸 bool QDomImplementation::hasFeature ( const QString & feature, const QString & version ) [virtual]

this one returns TRUE if QDom implements the requested version of a feature; otherwise it returns FALSE ✅❌

the currently supported features and their versions — and no, I'm not making this up, this is literally what the man page shows right here:

<center>.nf
</center>

🌸 bool QDomImplementation::isNull ()

returns FALSE if the object was created by QDomDocument::implementation(); otherwise returns TRUE 🙈

🌸 bool QDomImplementation::operator!= ( const QDomImplementation & x ) const

returns TRUE if x and this DOM implementation object were created from different QDomDocuments; otherwise returns FALSE 💀

🌸 QDomImplementation & QDomImplementation::operator= ( const QDomImplementation & x )

assigns x to this DOM implementation 📥

🌸 bool QDomImplementation::operator== ( const QDomImplementation & x ) const

returns TRUE if x and this DOM implementation object were created from the same QDomDocument; otherwise returns FALSE 🫶
