Abstract Value Members
- abstract def activeContractWithArgument(readers: Set[Party], contractId: ContractId)(connection: Connection): Option[RawContract]
- abstract def activeContractWithoutArgument(readers: Set[Party], contractId: ContractId)(connection: Connection): Option[String]
- abstract def archivedContracts(contractIds: Seq[ContractId], before: Offset)(connection: Connection): Map[ContractId, RawArchivedContract]
- abstract def assignedContracts(contractIds: Seq[ContractId])(connection: Connection): Map[ContractId, RawCreatedContract]
- abstract def createdContracts(contractIds: Seq[ContractId], before: Offset)(connection: Connection): Map[ContractId, RawCreatedContract]
- abstract def keyState(key: Key, validAt: Offset)(connection: Connection): KeyState
Sequential lookup of key states
- abstract def keyStates(keys: Seq[Key], validAt: Offset)(connection: Connection): Map[Key, KeyState]
Batch lookup of key states
Batch lookup of key states
If the backend does not support batch lookups, the implementation will fall back to sequential lookups
- abstract def supportsBatchKeyStateLookups: Boolean
Returns true if the batch lookup is implemented
