Member Data Documentation

QgsVectorFileWriter::ActionOnExistingFile QgsVectorFileWriter::SaveVectorOptions::actionOnExistingFile = CreateOrOverwriteFile

Action on existing file.

Definition at line 454 of file qgsvectorfilewriter.h.

QgsAttributeList QgsVectorFileWriter::SaveVectorOptions::attributes

Attributes to export (empty means all unless skipAttributeCreation is set)

Definition at line 477 of file qgsvectorfilewriter.h.

QgsCoordinateTransform QgsVectorFileWriter::SaveVectorOptions::ct

Transform to reproject exported geometries with, or invalid transform for no transformation.

Definition at line 462 of file qgsvectorfilewriter.h.

QStringList QgsVectorFileWriter::SaveVectorOptions::datasourceOptions

List of OGR data source creation options.

Definition at line 468 of file qgsvectorfilewriter.h.

QString QgsVectorFileWriter::SaveVectorOptions::driverName

OGR driver to use.

Definition at line 448 of file qgsvectorfilewriter.h.

QgsFeedback* QgsVectorFileWriter::SaveVectorOptions::feedback = nullptr

Optional feedback object allowing cancellation of layer save.

Definition at line 508 of file qgsvectorfilewriter.h.

QgsVectorFileWriter::FieldValueConverter* QgsVectorFileWriter::SaveVectorOptions::fieldValueConverter = nullptr

Field value converter.

Ownership is not transferred and callers must ensure that the lifetime of fieldValueConverter exceeds the lifetime of the QgsVectorFileWriter object.

Definition at line 505 of file qgsvectorfilewriter.h.

QString QgsVectorFileWriter::SaveVectorOptions::fileEncoding

Encoding to use.

Definition at line 457 of file qgsvectorfilewriter.h.

QgsRectangle QgsVectorFileWriter::SaveVectorOptions::filterExtent

If not empty, only features intersecting the extent will be saved.

Definition at line 486 of file qgsvectorfilewriter.h.

bool QgsVectorFileWriter::SaveVectorOptions::forceMulti = false

Sets to true to force creation of multi* geometries.

Definition at line 494 of file qgsvectorfilewriter.h.

bool QgsVectorFileWriter::SaveVectorOptions::includeZ = false

Sets to true to include z dimension in output. This option is only valid if overrideGeometryType is set.

Definition at line 497 of file qgsvectorfilewriter.h.

QString QgsVectorFileWriter::SaveVectorOptions::layerName

Layer name. If let empty, it will be derived from the filename.

Definition at line 451 of file qgsvectorfilewriter.h.

QStringList QgsVectorFileWriter::SaveVectorOptions::layerOptions

List of OGR layer creation options.

Definition at line 471 of file qgsvectorfilewriter.h.

bool QgsVectorFileWriter::SaveVectorOptions::onlySelectedFeatures = false

Write only selected features of layer.

Definition at line 465 of file qgsvectorfilewriter.h.

QgsWkbTypes::Type QgsVectorFileWriter::SaveVectorOptions::overrideGeometryType = QgsWkbTypes::Unknown

Set to a valid geometry type to override the default geometry type for the layer.

This parameter allows for conversion of geometryless tables to null geometries, etc

Definition at line 491 of file qgsvectorfilewriter.h.

bool QgsVectorFileWriter::SaveVectorOptions::skipAttributeCreation = false

Only write geometries.

Definition at line 474 of file qgsvectorfilewriter.h.
