Variable Loop End

KNIME Base Nodes version 4.1.2.v202003032313 by KNIME AG, Zurich, Switzerland

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).

Options

Variable selection: The variables that will be collected and put into the output table.

Input Ports

: Flow variables to collect.

Output Ports

: Data table with during the loop collected variables.
