Variable Condition Loop End

In combination with a "Variable Condition Loop (Start)" node, this node lets you execute the body of the loop until a certain condition on one of the flow variables is met. In the dialog you can choose one of the available flow variables and which condition should cause the loop to finish.

Dialog Options

Available variables
In the list you can select one of the available flow variables. Below the list, you can choose, when the loop's execution should be finished, i.e. when the selected variable is, equal, greater, greater or equal, smaller, or smaller or equal than the given value. For string variables only the check for equality is possible.
Collect rows from last iteration
The default is to collect the rows from all the loop's iterations, including the last one after which the loop is stopped. If you de-select this option, the rows from the last iteration are not added to the output table.
Collect rows from last iteration only
If only the rows from the very last iteration should be collected, you have to enable this option.
Add iteration column
Allows you to add a column containing the iteration number to the output table.
