Public Member Functions | |
void | addMappedField (const QString &destinationField, const QgsProperty &property) |
Adds a mapping for a destination field. | |
QgsCoordinateReferenceSystem | destinationCrs () const |
Returns the destination CRS used for reprojecting incoming features to the sink's destination CRS. | |
QgsFields | destinationFields () const |
Returns the fields for the destination sink. | |
Qgis::WkbType | destinationWkbType () const |
Returns the WKB geometry type for the destination. | |
QMap< QString, QgsProperty > | fieldMap () const |
Returns the field mapping, which defines how to map the values from incoming features to destination field values. | |
bool | loadVariant (const QVariantMap &map) |
Loads this remapping definition from a QVariantMap, wrapped in a QVariant. | |
bool | operator!= (const QgsRemappingSinkDefinition &other) const |
bool | operator== (const QgsRemappingSinkDefinition &other) const |
void | setDestinationCrs (const QgsCoordinateReferenceSystem &destination) |
Sets the destination crs used for reprojecting incoming features to the sink's destination CRS. | |
void | setDestinationFields (const QgsFields &fields) |
Sets the fields for the destination sink. | |
void | setDestinationWkbType (Qgis::WkbType type) |
Sets the WKB geometry type for the destination. | |
void | setFieldMap (const QMap< QString, QgsProperty > &map) |
Sets the field mapping, which defines how to map the values from incoming features to destination field values. | |
void | setSourceCrs (const QgsCoordinateReferenceSystem &source) |
Sets the source crs used for reprojecting incoming features to the sink's destination CRS. | |
QgsCoordinateReferenceSystem | sourceCrs () const |
Returns the source CRS used for reprojecting incoming features to the sink's destination CRS. | |
QVariant | toVariant () const |
Saves this remapping definition to a QVariantMap, wrapped in a QVariant. | |
Defines the parameters used to remap features when creating a QgsRemappingProxyFeatureSink.
The definition includes parameters required to correctly map incoming features to the structure of the destination sink, e.g. information about how to create output field values and how to transform geometries to match the destination CRS.

Adds a mapping for a destination field.
Field values are mapped using a QgsProperty source object, which allows either direct field value to field value mapping or use of QgsExpression expressions to transform values to the destination field.

Returns the destination CRS used for reprojecting incoming features to the sink's destination CRS.

bool QgsRemappingSinkDefinition::loadVariant | ( | const QVariantMap & | map | ) |
Loads this remapping definition from a QVariantMap, wrapped in a QVariant.
You can use QgsXmlUtils::readVariant to load it from an XML document.
