The QGeoServiceProviderFactory class is a factory class used as the plugin interface for services related to geographical information.
Implementers must provide a unique combination of providerName() and providerVersion() per plugin.
The other functions should be overridden if the plugin supports the associated set of functionality.
Destroys this QGeoServiceProviderFactory instance.
Returns a new QGeoMappingManagerEngine instance, initialized with parameters, which implements as much of the places searching functionality as the service provider supports.
If error is not 0 it should be set to QGeoServiceProvider::NoError on success or an appropriate QGeoServiceProvider::Error on failure.
If errorString is not 0 it should be set to a string describing any error which occurred.
The default implementation returns 0, which causes a QGeoServiceProvider::NotSupportedError in QGeoServiceProvider.
