Detailed Description

A multi-layer output for processing algorithms which create map layers, when the number and nature of the output layers is not predefined.

Note: Always prefer to explicitly define QgsProcessingOutputVectorLayer, QgsProcessingOutputRasterLayer or QgsProcessingOutputMapLayer where possible. QgsProcessingOutputMultipleLayers should only ever be used when the number of output layers is not fixed - e.g. as a result of processing all layers in a specified folder.
