Interface CommandCompletionServiceGrpc.AsyncService

  • All Known Implementing Classes:
    CommandCompletionServiceGrpc.CommandCompletionServiceImplBase
    Enclosing class:
    CommandCompletionServiceGrpc
    public static interface CommandCompletionServiceGrpc.AsyncService
     Allows clients to observe the status of their submissions.
 Commands may be submitted via the Command Submission Service.
 The on-ledger effects of their submissions are disclosed by the Transaction Service.
 Commands may fail in 2 distinct manners:
 1. Failure communicated synchronously in the gRPC error of the submission.
 2. Failure communicated asynchronously in a Completion, see ``completion.proto``.
 Note that not only successfully submitted commands MAY produce a completion event. For example, the participant MAY
 choose to produce a completion event for a rejection of a duplicate command.
 Clients that do not receive a successful completion about their submission MUST NOT assume that it was successful.
 Clients SHOULD subscribe to the CompletionStream before starting to submit commands to prevent race conditions.
