Detailed Description

The QDomCharacterData class represents a generic string in the DOM.

Note: This class or function is reentrant.

Attention: Module: QtXml

Character data as used in XML specifies a generic data string. More specialized versions of this class are QDomText, QDomComment and QDomCDATASection.

The data string is set with setData() and retrieved with data(). You can retrieve a portion of the data string using substringData(). Extra data can be appended with appendData(), or inserted with insertData(). Portions of the data string can be deleted with deleteData() or replaced with replaceData(). The length of the data string is returned by length().

The node type of the node containing this character data is returned by nodeType().

Constructors and Destructors

◆ QDomCharacterData() [1/3]

QDomCharacterData::QDomCharacterData ( )

Constructs an empty character data object.

Definition at line 4056 of file qdom.cpp.

4057 {

4058 }

◆ QDomCharacterData() [2/3]

QDomCharacterData::QDomCharacterData ( const QDomCharacterData & 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 4067 of file qdom.cpp.

     : QDomNode(x)

Functions

◆ appendData()

void QDomCharacterData::appendData ( const QString & arg )

 }

◆ nodeType()

QDomNode::NodeType QDomCharacterData::nodeType ( ) const

Returns the type of node this object refers to (i.e.

TextNode, CDATASectionNode, CommentNode or CharacterDataNode). For a null node, returns CharacterDataNode.

 {
     if (!impl)

     return QDomNode::nodeType();
 }

◆ operator=()

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

Assigns x to this character data.

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 4084 of file qdom.cpp.

 {
     return (QDomCharacterData&) QDomNode::operator=(x);
 }

◆ replaceData()

void QDomCharacterData::replaceData	(	unsigned long	offset,
		unsigned long	count,
		const QString &	arg
	)

Replaces the substring of length count starting at position offset with the string arg.

Definition at line 4162 of file qdom.cpp.

 {
     if (impl)
         IMPL->replaceData(offset, count, arg);
 }

◆ setData()

void QDomCharacterData::setData ( const QString & v )

Sets this object's string to v.

Definition at line 4105 of file qdom.cpp.

 {
     if (impl)
         impl->setNodeValue(v);
 }

◆ substringData()

QString QDomCharacterData::substringData	(	unsigned long	offset,
		unsigned long	count
	)

Returns the substring of length count from position offset.

Definition at line 4124 of file qdom.cpp.

 {
     if (!impl)
         return QString();
     return IMPL->substringData(offset, count);
