Detailed Description

The QVersitDefaultResourceHandler class provides a default implementation of a Versit resource handler.

An example resource handler implementation:

    class MyResourceHandler : public QVersitDefaultResourceHandler {
    public:
       bool saveResource(const QByteArray& contents, const QVersitProperty& property,
                         QString* location) {
           Q_UNUSED(property)
           *location = QString::number(qrand());
           QFile file(*location);
           file.open(QIODevice::WriteOnly);
           file.write(contents); // In a real implementation, consider when this file will be deleted.
           return true;
       }
       bool loadResource(const QString& location, QByteArray* contents, QString* mimeType)
       {
           return QVersitDefaultResourceHandler::loadResource(location, contents, mimeType);
       }
    };

Member Function Documentation

QVersitDefaultResourceHandler::QVersitDefaultResourceHandler ()

Constructs a QVersitDefaultResourceHandler.

QVersitDefaultResourceHandler::~QVersitDefaultResourceHandler ()   [virtual]

Frees any memory used by the resource handler.

bool QVersitDefaultResourceHandler::loadResource ( const QString & location, QByteArray * contents, QString * mimeType )   [virtual]

Default resource loader. Loads file from given location into contents and returns true if successful. Sets the mimeType based on the file extension.

Reimplemented from QVersitResourceHandler.

bool QVersitDefaultResourceHandler::saveResource ( const QByteArray & contents, const QVersitProperty & property, QString * location )   [virtual]

Default resource saver. Does nothing and returns false, ignoring contents, property and location. By default, resources aren't persisted because we don't know when it is safe to remove them.

Reimplemented from QVersitResourceHandler.
