             Summary: [proton-j] allow suppressing the synthentic flow event when sending transfers
                 Key: PROTON-1110
                 URL: https://issues.apache.org/jira/browse/PROTON-1110
             Project: Qpid Proton
          Issue Type: Bug
          Components: proton-j
    Affects Versions: 0.11.1
            Reporter: Robbie Gemmell
            Assignee: Robbie Gemmell
             Fix For: 0.12.0


The engine emits synthetic Flow events when sending messages, in addition to those raised when receiving a Flow frame for the link. I believe the reasoning for this is so to treat it as a 'credit changed' indicator. However, as there are cases where the decision to send a message has little at all to do with the credit conditions, having these events its often unecessary and wasteful.

A simple toggle will be added to signal the transport not to emit the flow events for use in those cases. The default behaviour will be unchanged.
