Recursive Loop Start

The Recursive Loop node pair enables the passing of data tables from the Recursive Loop End back to the Recursive Loop Start.

The Recursive Loop Start requires initialized tables. This tables are 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 the Recursive Loop Start node. Starting with the second iteration, the Recursive Loop Start node outputs the data as received by the Recursive Loop End.

You can add more initialized input tables and recursion output tables using the “…” menu. The number of recursion ports must be the same as the number of recursion ports of the corresponding Recursive Loop End node.

Input ports

1. Type: Table
   Initialization data
   The data tables used as initial values.

Output ports

1. Type: Table
   Recursion data
   The data from the loop end.

Recursion (Dynamic Inport)

The data tables used as initial values.

1. Type: Table

Recursion (Dynamic Outport)

The data from the loop end.

1. Type: Table
