Constructor & Destructor Documentation

◆ XmlHandler()

Isis::ShapeList::XmlHandler::XmlHandler ( ShapeList * shapeList,
Project * project )

Create an XML Handler (reader) that can populate the Shape list class data.

Parameters
shapeListThe shape list we're going to be initializing
projectThe project that contains the shape list
See also
ShapeList::save()

Definition at line 755 of file ShapeList.cpp.

Member Function Documentation

◆ endElement()

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

Handle an XML end element.

This handles <shapeList > by opening and reading the shapes.xml file.

Returns
bool If we should continue reading the XML (usually true).
Exceptions
IException::Io"Unable to open with read access"
IException::Io"Failed to open shape list XML"

Reimplemented from Isis::XmlStackedHandler.

◆ setReader()

void Isis::XmlStackedHandler::setReader ( XmlStackedHandlerReader * reader)
virtualinherited

Definition at line 28 of file XmlStackedHandler.cpp.

◆ startElement()

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

Handle an XML start element.

This expects <shapeList> and <shape> elements (it reads both the project XML and the shapes.xml file).

Returns
bool If we should continue reading the XML (usually true).

◆ switchToNewHandler()

void Isis::XmlStackedHandler::switchToNewHandler ( XmlStackedHandler * nextHandler)
inherited

Switch to a new content handler and continue processing using the new handler.
