- class qgis.core.QgsProcessingParameterFieldMapping¶
Bases:
QgsProcessingParameterDefinition
A parameter for “field mapping” configurations, which consist of a definition of desired output fields, types, and expressions used to populate then.
Designed for use with the “Refactor fields” algorithm.
New in version 3.14.
