  9. ACK vs. filter Translator instance


It is possible to customize the LLP listener component to invoke a Translator instance. This allows using the Translator instance to customize the response of the LLP listener component to allow applications like:

  • Custom ACK formats including XML formatted ACKs.
  • Application ACKs/NACKs as opposed to just protocol ACKs, i.e, “not only did I get your data but my application said it was okay!”
  • Responding to queries (i.e., query/response logic)

You can also send messages via LLP with the Translator. This allows you to send queries and apply sophisticated logic to responses and ACKs/NACKs.
