Abstract Value Members

  1. abstract def find(filterSource: Option[SourceDomainId], filterRequestTimestamp: Option[CantonTimestamp], filterSubmitter: Option[LfPartyId], limit: Int)(implicit traceContext: TraceContext): Future[Seq[TransferData]]

    Find utility to look for in-flight transfers.

    Find utility to look for in-flight transfers. Queried by com.digitalasset.canton.console.commands.ParticipantAdministration#transfer.search. Results need not be consistent with lookup.

  2. abstract def findAfter(requestAfter: Option[(CantonTimestamp, SourceDomainId)], limit: Int)(implicit traceContext: TraceContext): Future[Seq[TransferData]]

    Find utility to look for in-flight transfers.

    Find utility to look for in-flight transfers. Transfers are ordered by the tuple (request timestamp, source domain ID), ie transfers are ordered by request timestamps and ties are broken with lexicographic ordering on domain IDs.

    The ordering here has been chosen to allow a participant to fetch all the pending transfers. The ordering has to be consistent accross calls and uniquely identify a pending transfer, but is otherwise arbitrary.

    requestAfter

    optionally, specify a strict lower bound for the transfers returned, according to the (request timestamp, source domain ID) ordering

    limit

    limit the number of results

  3. abstract def findIncomplete(sourceDomain: Option[SourceDomainId], validAt: GlobalOffset, stakeholders: Option[NonEmpty[Set[LfPartyId]]], limit: NonNegativeInt)(implicit traceContext: TraceContext): Future[Seq[IncompleteTransferData]]

    Find utility to look for incomplete transfers.

    Find utility to look for incomplete transfers. Transfers are ordered by global offset.

    A transfer t is considered as incomplete at offset validAt if only one of the two transfer events was emitted on the multi-domain event log at validAt. That is, one of the following hold:

    1. Only transfer-out was emitted
      • t.transferOutGlobalOffset is smaller or equal to validAt
      • t.transferInGlobalOffset is null or greater than validAt 2. Only transfer-in was emitted
      • t.transferInGlobalOffset is smaller or equal to validAt
      • t.transferOutGlobalOffset is null or greater than validAt

    In particular, for a transfer to be considered incomplete at validAt, then exactly one of the two offsets (transferOutGlobalOffset, transferInGlobalOffset) is not null and smaller or equal to validAt.

    sourceDomain

    if empty, select only transfers whose source domain matches the given one

    validAt

    select only transfers that are successfully transferred-out

    stakeholders

    if non-empty, select only transfers of contracts whose set of stakeholders intersects stakeholders.

    limit

    limit the number of results

  4. abstract def lookup(transferId: TransferId)(implicit traceContext: TraceContext): EitherT[Future, TransferLookupError, TransferData]

    Looks up the given in-flight transfer and returns the data associated with the transfer.

    Looks up the given in-flight transfer and returns the data associated with the transfer.

    returns

    scala.Left$(TransferStore.UnknownTransferId) if the transfer is unknown; scala.Left$(TransferStore.TransferCompleted) if the transfer has already been completed.
