virtual QGeoCodingManagerEngine * | createGeocodingManagerEngine(const QVariantMap & parameters, QGeoServiceProvider::Error * error, QString * errorString) const
virtual QPlaceManagerEngine * | createPlaceManagerEngine(const QVariantMap & parameters, QGeoServiceProvider::Error * error, QString * errorString) const

## Detailed Description

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.

## 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.
