\class QGeoPositionInfoSourceFactory
\brief The QGeoPositionInfoSourceFactory class is a factory class used
as the plugin interface for external providers of positioning data.
\inmodule QtLocation
\ingroup location
Implementers must provide a unique combination of sourceName() and
sourceVersion() per plugin.
The other functions must be overridden by all plugins, other than
sourcePriority() which defaults to returning 0. Higher values of
priority will be preferred to lower ones.
\section1 Default plugins
Normally, the platform default position source will always overrule any
plugin-based position source during a call to createDefaultSource().
However, a limited measure is available where needed to change this behaviour,
using a system-wide configuration file.
The configuration file is in the system's default QSettings format, under
\c Nokia/QtLocationPosAndSat (for example, on most Linux variants this is
\c /etc/xdg/Nokia/QtLocationPosAndSat.conf). To set a default plugin source,
set the value \c position.plugin.operator.whitelist to a string of the format
\c "name,filename,hash,size" where \a name is the same as returned by the
plugin's \c sourceName() function, \a size is the size of the shared library
and \a hash is the library's SHA1 hash in hex format.
*/
/*!
\fn QGeoPositionInfoSource *QGeoPositionInfoSourceFactory::positionInfoSource(QObject *parent)
Returns a new QGeoPositionInfoSource associated with this plugin
with parent \a parent . Can also return 0, in which case the factory
with the next highest priority will be used instead.
*/
/*!
\fn QGeoSatelliteInfoSource *QGeoPositionInfoSourceFactory::satelliteInfoSource(QObject *parent)
Returns a new QGeoSatelliteInfoSource associated with this plugin
with parent \a parent. Can also return 0, in which case the factory
with the next highest priority will be used instead.
*/
/*!
\fn QString QGeoPositionInfoSourceFactory::sourceName() const
Returns the string used to identify the position provider behind this
implementation.
The combination of sourceName() and sourceVersion() should be unique
amongst the plugins.
*/
/*!
\fn int QGeoPositionInfoSourceFactory::sourceVersion() const
Returns the version of the plugin.
The combination of sourceName() and sourceVersion() should be unique
amongst the plugins.
*/
/*!
Returns the priority of this factory in the list of available
factories. Factories with higher values of priority will be preferred
to those with lower values.
*/
int QGeoPositionInfoSourceFactory::sourcePriority() const
{
return 0;
}
/*!
Destroys the position info source factory.
