Member Function Documentation

◆ destinationCrs()

QgsCoordinateReferenceSystem QgsVectorLayerExporter::ExportOptions::destinationCrs ( ) const

Returns the destination coordinate reference system used for exported features.

See also: setDestinationCrs()

Definition at line 72 of file qgsvectorlayerexporter.cpp.

◆ expressionContext()

const QgsExpressionContext & QgsVectorLayerExporter::ExportOptions::expressionContext ( ) const

Returns the expression context used when a filterExpression() is set.

See also: setExpressionContext()

Definition at line 102 of file qgsvectorlayerexporter.cpp.

◆ extent()

QgsReferencedRectangle QgsVectorLayerExporter::ExportOptions::extent ( ) const

Returns the extent filter for the features to export.

Only features with a bounding box intersecting this extent will be exported.

Note: This option only applies when the QgsVectorLayerExporter::exportLayer() method is used.

See also: setExtent()

Definition at line 82 of file qgsvectorlayerexporter.cpp.

◆ filterExpression()

QString QgsVectorLayerExporter::ExportOptions::filterExpression ( ) const

Returns the filter expression for features to export.

Only features matching this expression will be exported.

Warning: This setting is incompatible with selectedOnly()

Note: This option only applies when the QgsVectorLayerExporter::exportLayer() method is used.

See also: expressionContext(); setFilterExpression()

Definition at line 92 of file qgsvectorlayerexporter.cpp.

◆ outputFields()

QList< QgsVectorLayerExporter::OutputField > QgsVectorLayerExporter::ExportOptions::outputFields ( ) const

Returns the output field definitions for the destination table.

If empty, all input fields will be copied directly.

Note: This option only applies when the QgsVectorLayerExporter::exportLayer() method is used.

See also: setOutputFields()

Definition at line 107 of file qgsvectorlayerexporter.cpp.

◆ selectedOnly()

bool QgsVectorLayerExporter::ExportOptions::selectedOnly ( ) const

inline

Returns whether the export will only include selected features.

Warning: This setting is incompatible with filterExpression()

Note: This option only applies when the QgsVectorLayerExporter::exportLayer() method is used.

See also: setSelectedOnly()

Definition at line 130 of file qgsvectorlayerexporter.h.

◆ setDestinationCrs()

void QgsVectorLayerExporter::ExportOptions::setDestinationCrs ( const QgsCoordinateReferenceSystem & crs )

Sets the destination coordinate reference system to use for exported features.

See also: destinationCrs()

Definition at line 67 of file qgsvectorlayerexporter.cpp.

◆ setExpressionContext()

void QgsVectorLayerExporter::ExportOptions::setExpressionContext ( const QgsExpressionContext & context )

Sets the expression context to use when a filterExpression() is set.

See also: expressionContext()

Definition at line 97 of file qgsvectorlayerexporter.cpp.

◆ setExtent()

void QgsVectorLayerExporter::ExportOptions::setExtent ( const QgsReferencedRectangle & extent )

Sets an extent filter for the features to export.

Only features with a bounding box intersecting extent will be exported.

Note: This option only applies when the QgsVectorLayerExporter::exportLayer() method is used.

See also: extent()

Definition at line 77 of file qgsvectorlayerexporter.cpp.

◆ setFilterExpression()

void QgsVectorLayerExporter::ExportOptions::setFilterExpression ( const QString & expression )

Set the filter expression for the features to export.

Only features matching this expression will be exported.

Warning: This setting is incompatible with setSelectedOnly()

Note: This option only applies when the QgsVectorLayerExporter::exportLayer() method is used.

See also: setExpressionContext(); filterExpression()

Definition at line 87 of file qgsvectorlayerexporter.cpp.

◆ setOutputFields()

void QgsVectorLayerExporter::ExportOptions::setOutputFields ( const QList< QgsVectorLayerExporter::OutputField > & fields )

Sets the output field definitions for the destination table.

If empty, all input fields will be copied directly.

Note: This option only applies when the QgsVectorLayerExporter::exportLayer() method is used.

See also: outputFields()

Definition at line 112 of file qgsvectorlayerexporter.cpp.

◆ setSelectedOnly()

void QgsVectorLayerExporter::ExportOptions::setSelectedOnly ( bool selected )

inline

Sets whether the export should only include selected features.

Warning: This setting is incompatible with setFilterExpression()

Note: This option only applies when the QgsVectorLayerExporter::exportLayer() method is used.

See also: selectedOnly()

Definition at line 119 of file qgsvectorlayerexporter.h.

◆ setTransformContext()

void QgsVectorLayerExporter::ExportOptions::setTransformContext ( const QgsCoordinateTransformContext & context )

Sets the coordinate transform context to use when transforming exported features.

See also: transformContext()

Definition at line 57 of file qgsvectorlayerexporter.cpp.

◆ transformContext()

QgsCoordinateTransformContext QgsVectorLayerExporter::ExportOptions::transformContext ( ) const

Returns the coordinate transform context used when transforming exported features.

See also: setTransformContext()
