DITBusStreamDelegate

@protocol DITBusStreamDelegate <NSObject>

Callbacks required to use the Ditto Bus API with explicit stream handles.

  • The operation to enqueue outgoing data on a stream has completed. More data may now be enqueued.

    The message sequence number may be used to track when the remote side has fully acknowledged receipt.

    error will be non-nil if the operation failed.

    Declaration

    Objective-C

    - (void)ditBusStream:(DITBusStream *)busStream
    didEnqueueDataWithMessageSequence:(uint64_t)messageSequence
                                error:(NSError *)error;

  • The stream has closed. This can be triggered by calling close() or by the remote peer doing the same.
