QGeoServiceProvider::​QGeoServiceProvider(const QString & providerName, const QVariantMap & parameters = QVariantMap(), bool allowExperimental = false)

Constructs a QGeoServiceProvider whose backend has the name providerName, using the provided parameters.

If multiple plugins have the same providerName, the plugin with the highest reported providerVersion() will be used.

If allowExperimental is true then plugins marked as experimental may be used. By default experimental plugins are not considered.

If no plugin matching providerName was able to be loaded then error() and errorString() will provide details about why this is the case.

QGeoServiceProvider::​~QGeoServiceProvider()

Destroys the service provider object.

[static] QStringList QGeoServiceProvider::​availableServiceProviders()

Returns a list of names of the available service providers, for use with the QGeoServiceProvider constructors.

Error QGeoServiceProvider::​error() const

Returns an error code describing the error which occurred during the last operation that was performed by this class.

QString QGeoServiceProvider::​errorString() const

Returns a string describing the error which occurred during the last operation that was performed by this class.

GeocodingFeatures QGeoServiceProvider::​geocodingFeatures() const

Returns the geocoding features supported by the geo service provider.

QGeoCodingManager * QGeoServiceProvider::​geocodingManager() const

Returns the QGeoCodingManager made available by the service provider.

This function will return 0 if the service provider does not provide any geocoding services.

This function will attempt to construct a QGeoCodingManager instance when it is called for the first time. If the attempt is successful the QGeoCodingManager will be cached, otherwise each call of this function will attempt to construct a QGeoCodingManager instance until the construction is successful.

The QGeoCodingManager is owned by this QGeoServiceProvider and should not be deleted separately. Users should assume that deleting the QGeoServiceProvider renders the pointer returned by this method invalid.

After this function has been called, error() and errorString() will report any errors which occurred during the construction of the QGeoCodingManager.

MappingFeatures QGeoServiceProvider::​mappingFeatures() const

Returns the mapping features supported by the geo service provider.

QPlaceManager * QGeoServiceProvider::​placeManager() const

Returns the QPlaceManager made available by the service provider.

This function will attempt to construct a QPlaceManager instance when it is called for the first time. If the attempt is successful the QPlaceManager will be cached, otherwise each call of this function will attempt to construct a QPlace instance until the construction is successful.

The QGeoPlaceManager is owned by this QGeoServiceProvider and should not be deleted separately. Users should assume that deleting the QGeoServiceProvider renders the pointer returned by this method invalid.

After this function has been called, error() and errorString() will report any errors which occurred during the construction of the QPlaceManager.

PlacesFeatures QGeoServiceProvider::​placesFeatures() const

Returns the places features supported by the geo service provider.

RoutingFeatures QGeoServiceProvider::​routingFeatures() const

Returns the routing features supported by the geo service provider.

QGeoRoutingManager * QGeoServiceProvider::​routingManager() const

Returns the QGeoRoutingManager made available by the service provider.

This function will return 0 if the service provider does not provide any geographic routing services.

This function will attempt to construct a QGeoRoutingManager instance when it is called for the first time. If the attempt is successful the QGeoRoutingManager will be cached, otherwise each call of this function will attempt to construct a QGeoRoutingManager instance until the construction is successful.

The QGeoRoutingManager is owned by this QGeoServiceProvider and should not be deleted separately. Users should assume that deleting the QGeoServiceProvider renders the pointer returned by this method invalid.

After this function has been called, error() and errorString() will report any errors which occurred during the construction of the QGeoRoutingManager.

void QGeoServiceProvider::​setAllowExperimental(bool allow)

Sets whether experimental plugins are considered when locating the correct plugin library for this service provider to allow.

Important: this will destroy any existing managers held by this service provider instance. You should be sure not to attempt to use any pointers that you have previously retrieved after calling this method.

void QGeoServiceProvider::​setLocale(const QLocale & locale)

Sets the locale used by this service provider to locale. If the relevant features (see LocalizedMappingFeature etc), this will change the languages, units and other locale-specific attributes of the provider's data.

void QGeoServiceProvider::​setParameters(const QVariantMap & parameters)

Sets the parameters used to construct individual manager classes for this service provider to parameters.

Important: this will destroy any existing managers held by this service provider instance. You should be sure not to attempt to use any pointers that you have previously retrieved after calling this method.
