Detailed Description

The QVersitContactHandlerFactory class provides the interface for Versit plugins.

This class provides a simple interface for the creation of QVersitContactHandler instances. Implement this interface to write a Versit plugin. For more details, see Versit Plugins.

Member Function Documentation

QVersitContactHandlerFactory::~QVersitContactHandlerFactory () [virtual]

This frees any memory used by the QVersitContactHandlerFactory.

QVersitContactHandler * QVersitContactHandlerFactory::createHandler () const [pure virtual]

This function is called by the Versit importer or exporter class to create an instance of the handler provided by this factory.

int QVersitContactHandlerFactory::index () const [virtual]

This function should return an index that helps with determining the order in which to run the plugins. Plugins are run in the following order:

  • Positively-indexed, ascending
  • Zero-indexed
  • Negatively-indexed, ascending

For example, plugins with an index of 1 are run first and plugins of index -1 are run last. If more than one plugin share an index, the order of execution between them is undefined.

By default, this returns 0, which is recommended for plugins with no special ordering requirements.

QString QVersitContactHandlerFactory::name () const [pure virtual]

This function should return a unique string that identifies the handlers provided by this factory. Typically, this will be of the form "com.nokia.qt.mobility.versit.samplehandler" with the appropriate domain and handler name substituted.

QSet<QString> QVersitContactHandlerFactory::profiles () const [virtual]

This function can be overridden to allow a plugin to report which profiles it is to be active under. If this (as in the default case) returns the empty set, it indicates that the plugin should be loaded under all profiles. If it returns a non-empty set, it will only be loaded for those profiles that are specified by the importer/exporter class.

Member Variable Documentation

const QLatin1Constant QVersitContactHandlerFactory::ProfileBackup

The constant string signifying a plugin that will backup a QContact to vCard, so that exporting, then importing a contact will not lose any data.

See also profiles(), QVersitContactImporter::QVersitContactImporter(), and QVersitContactExporter::QVersitContactExporter().

const QLatin1Constant QVersitContactHandlerFactory::ProfileSync

The constant string signifying a plugin that is relevant to import and export in a synchronization context.

See also profiles(), QVersitContactImporter::QVersitContactImporter(), and QVersitContactExporter::QVersitContactExporter().
