Detailed Description

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.

Since: QGIS 3.14

Member Function Documentation

◆ addMappedField()

void QgsRemappingSinkDefinition::addMappedField	(	const QString &	destinationField,
		const QgsProperty &	property
	)

inline

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.

See also: setFieldMap(); fieldMap()

Definition at line 75 of file qgsremappingproxyfeaturesink.h.

◆ destinationCrs()

QgsCoordinateReferenceSystem QgsRemappingSinkDefinition::destinationCrs ( ) const

inline

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

See also: setDestinationCrs()

Definition at line 96 of file qgsremappingproxyfeaturesink.h.

◆ destinationFields()

QgsFields QgsRemappingSinkDefinition::destinationFields ( ) const

inline

Returns the fields for the destination sink.

See also: setDestinationFields()

Definition at line 124 of file qgsremappingproxyfeaturesink.h.

◆ destinationWkbType()

Qgis::WkbType QgsRemappingSinkDefinition::destinationWkbType ( ) const

inline

Returns the WKB geometry type for the destination.

See also: setDestinationWkbType()

Definition at line 110 of file qgsremappingproxyfeaturesink.h.

◆ fieldMap()

QMap< QString, QgsProperty > QgsRemappingSinkDefinition::fieldMap ( ) const

inline

Returns the field mapping, which defines how to map the values from incoming features to destination field values.

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.

See also: setFieldMap(); addMappedField()

Definition at line 52 of file qgsremappingproxyfeaturesink.h.

◆ loadVariant()

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.

◆ setFieldMap()

void QgsRemappingSinkDefinition::setFieldMap ( const QMap< QString, QgsProperty > & map )

inline

Sets the field mapping, which defines how to map the values from incoming features to destination field values.

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.
