Type Members

1.  sealed trait AcceptRejectError extends AnyRef
2.  class AcceptRejectException extends RuntimeException

   Exception to carry the accept reject error where a Future[Unit] return is expected (transaction processing)

3.  case class AdminWorkflowConfig(bongTestMaxLevel: Long = 0, retries: Int = 10, submissionTimeout: NonNegativeFiniteDuration = NonNegativeFiniteDuration.ofHours(1), autoloadDar: Boolean = true) extends Product with Serializable

   Configuration options for Canton admin workflows like participant.health.ping

   Configuration options for Canton admin workflows like participant.health.ping

   bongTestMaxLevel

   Upper bound on the level of a bong that the participant can initiate. The participant can still participate in bongs at higher levels. Use this to limit the load the participants can cause by initiating bongs.

   retries

   The maximum number of times the com.digitalasset.canton.participant.ledger.api.client.CommandSubmitterWithRetry will retry an admin command submitted to the com.digitalasset.canton.participant.admin.AdminWorkflowServices.

   submissionTimeout

   Defines how long an admin workflow waits until it observes a completion for its command submissions before it assumes that the submission is lost and retries. If a lower timeout value is specified for an admin workflow, they take precedence.

4.  trait AdminWorkflowService extends AutoCloseable

   Admin service that connects to the ledger and process events

5.  class AdminWorkflowServices extends FlagCloseableAsync with NamedLogging with Spanning with NoTracing

   Manages our admin workflow applications (ping, dar distribution).

   Manages our admin workflow applications (ping, dar distribution). Currently each is individual application with their own ledger connection and acting independently.

6.  trait DarDistribution extends AnyRef

   Dar distribution operations

7.  class DarDistributionService extends AdminWorkflowService with DarDistribution with NamedLogging
8.  trait DarService extends AnyRef
9.  class DeduplicatingPackageLoader extends AnyRef
10.  class DomainConnectivityService extends NamedLogging
11.  class EnterpriseResourceManagementService extends ResourceManagementService
12.  class InMemoryShareOfferStore extends InMemorySimpleTrackerStore[ShareDar] with ShareOfferStore
13.  class InMemoryShareRequestStore extends InMemorySimpleTrackerStore[ShareDar] with ShareRequestStore
14.  class InMemorySimpleTrackerStore[A] extends SimpleContractTrackerStore[A]
15.  class InMemoryWhitelistStore extends WhitelistStore
16.  trait PackageInspectionOps extends NamedLogging
17.  class PackageInspectionOpsImpl extends PackageInspectionOps
18.  class PackageService extends DarService with PackageInfoService with NamedLogging with FlagCloseable
19.  class PingService extends AdminWorkflowService with FlagCloseableAsync with NamedLogging

    Implements the core of the ledger ping service for a participant.

    Implements the core of the ledger ping service for a participant. The service measures the time needed for a nanobot on the responder to act on a contract created by the initiator.

    The main functionality: 1. once instantiated, it automatically starts a Scala Nanobot that responds to pings for this participant 2. it provides a ping method that sends a ping to the given (target) party

    Parameters:

    Annotations

    @SuppressWarnings()

20.  class RepairService extends NamedLogging with FlagCloseableAsync with HasCloseContext

    Implements the repair commands.

    Implements the repair commands. Repair commands work only if the participant has disconnected from the affected domains. Every individual repair commands is executed transactionally, i.e., either all its effects are applied or none. This is achieved in the same way as for request processing:

    • A request counter is allocated for the repair request (namely the clean request head) and marked as com.digitalasset.canton.participant.protocol.RequestJournal.RequestState.Pending. The repair request's timestamp is the timestamp where processing starts again upon reconnection to the domain.
    • All repair effects are persisted to the stores using the repair request counter.
    • The clean request prehead is advanced to the repair request counter. This commits the changes. If multiple domains are involved, transactionality is ensured via the com.digitalasset.canton.resource.TransactionalStoreUpdate mechanism.

    If anything goes wrong before advancing the clean request prehead, the already persisted data will be cleaned up upon the next repair request or reconnection to the domain.

21.  case class ResourceLimits(maxDirtyRequests: Option[NonNegativeInt], maxRate: Option[NonNegativeInt], maxBurstFactor: PositiveDouble = ResourceLimits.defaultMaxBurstFactor) extends Product with Serializable

    Encapsulated resource limits for a participant.

    Encapsulated resource limits for a participant.

    maxDirtyRequests

    the maximum number of requests that are currently being validated. This also covers requests submitted by other participants.

    maxRate

    the maximum rate at which commands may be submitted through the ledger api.

    maxBurstFactor

    to ratio of the max rate, describing the maximum acceptable initial burst before the steady rate limiting kicks in. example: if maxRate is 100 and the burst ratio is 0.3, then the first 30 commands can submitted in the same instant, while thereafter, only one command every 10ms is accepted.

22.  trait ResourceManagementService extends AnyRef
23.  sealed trait ShareError extends AnyRef
24.  trait ShareOfferStore extends SimpleContractTrackerStore[ShareDar]

    Store for received DAR sharing offers I've not yet responded to

25.  trait ShareRequestStore extends SimpleContractTrackerStore[ShareDar]

    Store for DAR sharing requests I've sent that haven't yet been accepted or rejected

26.  trait SimpleContractTrackerStore[A] extends AnyRef

27.  class SyncStateInspection extends NamedLogging

    Implements inspection functions for the sync state of a participant node

28.  class TransferService extends AnyRef
29.  trait WhitelistStore extends AnyRef

    Store for parties I have whitelisted DARs from (permitting them to be automatically installed)
