Class CommandSubmissionServiceGrpc.CommandSubmissionServiceImplBase

java.lang.Object

com.daml.ledger.api.v1.CommandSubmissionServiceGrpc.CommandSubmissionServiceImplBase

All Implemented Interfaces:

io.grpc.BindableService

Enclosing class:

CommandSubmissionServiceGrpc

public abstract static class CommandSubmissionServiceGrpc.CommandSubmissionServiceImplBase
extends java.lang.Object
implements io.grpc.BindableService

 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.

Method Detail

submit

public void submit(CommandSubmissionServiceOuterClass.SubmitRequest request,
                   io.grpc.stub.StreamObserver<com.google.protobuf.Empty> responseObserver)

 Submit a single composite command.
 Errors:
 - ``UNAUTHENTICATED``: if the request does not include a valid access token
 - ``PERMISSION_DENIED``: if the claims in the token are insufficient to perform a given operation
 - ``NOT_FOUND``: if the request does not include a valid ledger id or if a resource is missing (e.g. contract key)
 due to for example contention on resources
 - ``ALREADY_EXISTS`` if a resource is duplicated (e.g. contract key)
 - ``INVALID_ARGUMENT``: if the payload is malformed or is missing required fields
 - ``ABORTED``: if the number of in-flight commands reached the maximum (if a limit is configured)
 - ``FAILED_PRECONDITION``: on consistency errors (e.g. the contract key has changed since the submission)
 or if an interpretation error occurred
 - ``UNAVAILABLE``: if the participant is not yet ready to submit commands or if the service has been shut down.
