Loop

Updated

Description

This Action is used to execute a specific part of the Flow in a loop. The Action should be placed at the beginning of the part of the Flow that will be executed in a loop and is entered at the Start input, and at the end of that part of the Flow it should be returned to this Action, but now through the Next input.
Each time the Flow passes through this Action, the value of the set variable will change from the From to the To value with the Step value.
Flow execution will go through (From - To + 1) / Math.abs(step) times before the iteration completes, and passes through the Done output.
If we want to stop the iteration before the To value is reached, then we simply don’t need to return to the Next input. Also, it is possible to use SetVariable to change the variable by which it is iterated, and thus skip one or more steps.

Properties

Specific

Variable

ASSIGNABLE EXPRESSION (integer)

A variable that determines the number of passes through the loop and whose value will be changed and tested to see if a new iteration is needed.

From

EXPRESSION (integer)

The initial value of the variable.

To

EXPRESSION (integer)

The final value of the variable.

Step

EXPRESSION (integer)

The value by which the variable is changed on each pass. It can be a positive or negative number.

Inputs

start

SEQ | MANDATORY

When this input is passed, the variable is set to the From value and Flow execution continues through seqout.

next

SEQ | MANDATORY

When this input is passed, the variable is changed by the Step value. It is tested whether it is less than or equal to To value if Step is positive, or whether it is greater than or equal to if Step is negative.

If the variable has not exceeded the To value, then Flow execution continues through seqout, otherwise it continues through Done output.

Outputs

seqout

SEQ | MANDATORY

Flow execution continues through this output for the duration of the iteration.

done

SEQ | OPTIONAL

Flow execution continues through this output when the iteration is complete.
