Member Function Documentation

◆ error()

QString QgsVectorWarper::error ( ) const
inline

Returns the last error obtained during transformation.

Definition at line 66 of file qgsvectorwarper.h.

◆ transformFeatures()

bool QgsVectorWarper::transformFeatures ( QgsFeatureIterator iterator,
QgsFeatureSink sink,
const QgsCoordinateTransformContext context,
QgsFeedback feedback = nullptr 
) const

Transforms the features from iterator and adds the results to the specified sink.

The optional feedback argument can be used for progress reporting and cancellation.

Returns
true if all features were successfully transformed
