Constructor & Destructor Documentation

◆ XmlHandler()

Isis::ShapeDisplayProperties::XmlHandler::XmlHandler ( ShapeDisplayProperties * displayProperties )

Constructor for the XmlHandler class.

This is a child class of XmlStackedHandler, which is used by XmlStackedHandlerReader to parse an XML file.

Parameters

displayProperties Pointer to a ShapeDisplayProperties object.

Definition at line 197 of file ShapeDisplayProperties.cpp.

Member Function Documentation

◆ characters()

bool Isis::ShapeDisplayProperties::XmlHandler::characters ( const QString & ch )

virtual

This is called when the XML processor has parsed a chunk of character data.

This implementation of a virtual function calls QXmlDefaultHandler::characters(QString &ch) which in turn calls QXmlContentHandler::characters(QString &ch) which is called when the XML processor has parsed a chunk of character data.

See also: XmlStackedHandler, QXmlDefaultHandler,QXmlContentHandler

Parameters

ch	The character data.

Returns: bool Returns True if there were no problems with the character processing. It returns False if there was a problem, and the XML reader stops.

Definition at line 240 of file ShapeDisplayProperties.cpp.

◆ endElement()

bool Isis::ShapeDisplayProperties::XmlHandler::endElement	(	const QString &	namespaceURI,
		const QString &	localName,
		const QString &	qName
	)

virtual

The XML reader invokes this method at the end of every element in the XML document.

Parameters

namespaceURI	The Uniform Resource Identifier of the namespace (eg. "xmlns")
localName	The local name string (eg. "xhtml")
qName	The XML qualified string (eg. "xmlns:xhtml"). This can be empty if QNames are not available.

Returns: bool If this function returns True, then a signal is sent to the reader indicating the end of the element. If this function returns False, something bad happened and processing stops.

Reimplemented from Isis::XmlStackedHandler.

Definition at line 259 of file ShapeDisplayProperties.cpp.

◆ startElement()

bool Isis::ShapeDisplayProperties::XmlHandler::startElement	(	const QString &	namespaceURI,
		const QString &	localName,
		const QString &	qName,
		const QXmlAttributes &	atts
	)

virtual

This overrides the parent startElement function in XmlStackedHandler so the parser can handle an XML file containing ShapeDisplayProperties information.

Parameters

namespaceURI	The Uniform Resource Identifier of the element's namespace
localName	The local name string
qName	The XML qualified string (or empty, if QNames are not available).
atts	The XML attributes attached to each element
