For Node

The For Node provides the functionality to split an incoming packet into multiple sub-packets for repeated processing. This is useful in data processing flows where repeated tasks are needed, and it integrates the results of each sub-packet before returning them.

Specification

• No additional arguments are required.

Ports

• in: Receives packets from external sources and initiates the repeat operation. If the input is an array, each element is split into sub-packets and processed individually. If the input is not an array, it will be processed only once.
• out[0]: Passes the split sub-packets to the first output port.
• out[1]: Aggregates the results of all sub-packet processing and passes them to the second output port.
• error: Sends any errors encountered during processing to the external environment.

Example

- kind: for
  ports:
    out[0]:
      - name: next
        port: out
    out[1]:
      - name: done
        port: out
