Detailed Description

Interface for geocoders.

QgsGeocoderInterface implementations are able to take either a QgsFeature or a free-form string and calculate the corresponding geometry of the feature.

Member Function Documentation

appendedFields()

QgsFields QgsGeocoderInterface::appendedFields ( ) const

virtual

Returns a set of newly created fields which will be appended to existing features during the geocode operation.

These fields will include any extra content returned by the geocoder, such as fields for accuracy of the match or correct attribute values.

Reimplemented in QgsNominatimGeocoder, and QgsGoogleMapsGeocoder.

Definition at line 25 of file qgsgeocoder.cpp.

flags()

virtual Flags QgsGeocoderInterface::flags ( ) const

pure virtual

Returns the geocoder's capability flags.

Implemented in QgsNominatimGeocoder, and QgsGoogleMapsGeocoder.

geocodeFeature()

QList< QgsGeocoderResult > QgsGeocoderInterface::geocodeFeature ( const QgsFeature &  feature, const QgsGeocoderContext &  context, QgsFeedback *  feedback = nullptr  ) const

virtual

Geocodes a feature.

If implemented by the geocoder (i.e. flags() returns the QgsGeocoderInterface::Flag::GeocodesFeatures flag), a list of matching results will be returned.

The optional feedback argument can be used to provider cancellation support.

Definition at line 18 of file qgsgeocoder.cpp.

geocodeString()

QList< QgsGeocoderResult > QgsGeocoderInterface::geocodeString ( const QString &  string, const QgsGeocoderContext &  context, QgsFeedback *  feedback = nullptr  ) const

virtual

Geocodes a string.

If implemented by the geocoder (i.e. flags() returns the QgsGeocoderInterface::Flag::GeocodesStrings flag), a list of matching results will be returned.

The optional feedback argument can be used to provider cancellation support.

Reimplemented in QgsNominatimGeocoder, and QgsGoogleMapsGeocoder.

Definition at line 29 of file qgsgeocoder.cpp.

wkbType()

QgsWkbTypes::Type QgsGeocoderInterface::wkbType ( ) const

virtual

Returns the WKB type of geometries returned by the geocoder.

If this is not known in advance then QgsWkbTypes::Unknown should be returned (e.g. in the case that a geocoder may return different geometry types depending on the quality of the match).

Reimplemented in QgsNominatimGeocoder, and QgsGoogleMapsGeocoder.
