Variable Loop End

Node collecting variables created in a loop. This node closes a loop but does not aggregate data created in the loop but only variables. It can be used to close loops where all the magic happens in the loop itself and no aggregated output is needed. One instance could be a loop over a list of files, whereby each file is processed in one loop iteration (including writing one output file for each input).

Input ports

1. Type: Flow Variable
   Flow variables
   Flow variables to collect.

Output ports

1. Type: Table
   Data table of flow variables
   Data table with during the loop collected variables.
