Detailed Description

The QDomComment class represents an XML comment.

Note
This class or function is reentrant.
Attention
Module: QtXml

A comment in the parsed XML such as this:

<!-- this is a comment -->

is represented by QDomComment objects in the parsed Dom tree.

For further information about the Document Object Model see http://www.w3.org/TR/DOM-Level-2-Core/. For a more general introduction of the DOM implementation see the QDomDocument documentation.

Constructors and Destructors

◆ QDomComment() [1/3]

QDomComment::QDomComment ( )

Constructs an empty comment.

To construct a comment with content, use the QDomDocument::createComment() function.

Definition at line 5490 of file qdom.cpp.

5491  : QDomCharacterData()
5492 {
5493 }
QDomCharacterData()
Constructs an empty character data object.
Definition: qdom.cpp:4056

◆ QDomComment() [2/3]

QDomComment::QDomComment ( const QDomComment x)

Constructs a copy of x.

The data of the copy is shared (shallow copy): modifying one node will also change the other. If you want to make a deep copy, use cloneNode().

Definition at line 5502 of file qdom.cpp.

5503  : QDomCharacterData(x)
5504 {
5505 }
QDomCharacterData()
Constructs an empty character data object.
Definition: qdom.cpp:4056

◆ QDomComment() [3/3]

QDomComment::QDomComment ( QDomCommentPrivate n)
private

Definition at line 5507 of file qdom.cpp.

5508  : QDomCharacterData(n)
5509 {
5510 }
QDomCharacterData()
Constructs an empty character data object.
Definition: qdom.cpp:4056

Functions

◆ nodeType()

QDomNode::NodeType QDomComment::nodeType ( ) const
inline

Returns CommentNode.

Definition at line 563 of file qdom.h.

563 { return CommentNode; }

◆ operator=()

QDomComment & QDomComment::operator= ( const QDomComment x)

Assigns x to this DOM comment.

The data of the copy is shared (shallow copy): modifying one node will also change the other. If you want to make a deep copy, use cloneNode().

Definition at line 5519 of file qdom.cpp.

5520 {
5521  return (QDomComment&) QDomNode::operator=(x);
5522 }
QDomNode & operator=(const QDomNode &)
Assigns a copy of n to this DOM node.
