For Each Loop

Iterates over an array or map, executing a sub-graph for each item.

This node iterates over each item in an Iterable (such as an array or a map).

Execution Flow#

  1. The loop starts when the Execute input is triggered.
  2. For each item in the input array/map, the node: - Sets the Key and Value output ports. - Triggers the Body execution output.
  3. The Break input can be triggered at any time (e.g., from within the Body execution path) to stop the loop.
  4. After all items have been processed, or if the loop was stopped by the Break input, the Completed execution output is triggered.

Ports#

  • Key: For an array, this is the numeric index. For a map, this is the key.
  • Value: The value of the element at the current key/index.
