QFlags< ProcessingAlgorithmFlag > ProcessingAlgorithmFlags
Flags indicating how and when an algorithm operates and should be exposed to users.
Definition qgis.h:3076
@ HideFromToolbox
Algorithm should be hidden from the toolbox.
@ SkipGenericModelLogging
When running as part of a model, the generic algorithm setup and results logging should be skipped.
Contains information about the context in which a processing algorithm is executed.
Base class for providing feedback from a processing algorithm.
A string output for processing algorithms.
A string parameter for processing algorithms.
