KNIME Base Nodes version 3.6.0.v201807061308 by KNIME AG, Zurich, Switzerland
The Recursive Loop node pair enables the passing of two data tables from the Recursive Loop End's input ports 1 and 2 back to the Recursive Loop Start's output ports 0 and 1.
The Loop Start requires an initialized table. This table is output by the Recursive Loop Start in the first iteration of the loop.
The tables received by the corresponding Recursive Loop End are passed back to a Recursive Loop Start node. Starting with the second iteration, the Recursive Loop Start node outputs the data as received by the Recursive Loop End.
