Interface CommandSubmissionServiceGrpc.AsyncService

  • All Known Implementing Classes:
    CommandSubmissionServiceGrpc.CommandSubmissionServiceImplBase
    Enclosing class:
    CommandSubmissionServiceGrpc
    public static interface CommandSubmissionServiceGrpc.AsyncService
     Allows clients to attempt advancing the ledger's state by submitting commands.
 The final states of their submissions are disclosed by the Command Completion 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.
