      onMultiPartUploadComplete

      void onMultiPartUploadComplete(List<Result> uploadResults)
      This method is called when all the parts of a multi-part upload have been completed successfully.

      The list contains a Result for every stage of the job, in the order they were executed: the initiating stage, one entry per uploaded part, and finally the completing stage. Only the completing stage reports the uploaded file through Result.getFullFileNames(); for the other stages that list is empty. Use Result.getUploadInfo() to tell the stages apart.

      Parameters:
      uploadResults - - List of Result objects, one per stage.

      onMultiPartUploadCancel

      default void onMultiPartUploadCancel(List<Result> uploadResults)
      This method is called when a multi-part upload was aborted because an earlier stage of the job failed. It is never the result of an explicit request to cancel, as no such operation is exposed.

      The list contains a Result for every stage that completed before the failure, followed by the cancelling stage; none of them report an uploaded file, since nothing was committed. This callback is purely informational — the failure is also reported to the caller of the upload method as a thrown GPUdbException, which remains the authoritative error channel.

      Parameters:
      uploadResults - - List of Result objects, one per stage.

      Parameters:
      result - - a Result object
