This class was introduced in Qt 5.6.

Public Functions

virtual ~QGeoServiceProviderFactory()
virtual QGeoCodingManagerEngine *createGeocodingManagerEngine(const QVariantMap &parameters, QGeoServiceProvider::Error *error, QString *errorString) const
virtual QPlaceManagerEngine *createPlaceManagerEngine(const QVariantMap &parameters, QGeoServiceProvider::Error *error, QString *errorString) const
virtual QGeoRoutingManagerEngine *createRoutingManagerEngine(const QVariantMap &parameters, QGeoServiceProvider::Error *error, QString *errorString) const

Detailed Description

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.

Member Function Documentation

[virtual] QGeoServiceProviderFactory::~QGeoServiceProviderFactory()

Destroys this QGeoServiceProviderFactory instance.

[virtual] QGeoCodingManagerEngine *QGeoServiceProviderFactory::createGeocodingManagerEngine(const QVariantMap &parameters, QGeoServiceProvider::Error *error, QString *errorString) const

Returns a new QGeoCodingManagerEngine instance, initialized with parameters, which implements the location geocoding functionality.

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.

[virtual] QPlaceManagerEngine *QGeoServiceProviderFactory::createPlaceManagerEngine(const QVariantMap &parameters, QGeoServiceProvider::Error *error, QString *errorString) const

Returns a new QPlaceManagerEngine instance, initialized with parameters, which implements the place searching functionality.

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.

[virtual] QGeoRoutingManagerEngine *QGeoServiceProviderFactory::createRoutingManagerEngine(const QVariantMap &parameters, QGeoServiceProvider::Error *error, QString *errorString) const

Returns a new QGeoRoutingManagerEngine instance, initialized with parameters, which implements routing functionality.

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.
