class CordaRPCOpsImpl : CordaRPCOps
Server side implementations of RPCs available to MQ based client tools. Execution takes place on the server thread (i.e. serially). Arguments are serialised and deserialised automatically.

CordaRPCOpsImpl(services: ServiceHub, smm: StateMachineManager, database: Database)
Server side implementations of RPCs available to MQ based client tools. Execution takes place on the server thread (i.e. serially). Arguments are serialised and deserialised automatically. |
database |
val database: Database |
protocolVersion |
val protocolVersion: Int
Returns the RPC protocol version. Exists since version 0 so guaranteed to be present. |
services |
val services: ServiceHub |
smm |
val smm: StateMachineManager |
addVaultTransactionNote |
fun addVaultTransactionNote(txnId: SecureHash, txnNote: String): Unit |
attachmentExists |
fun attachmentExists(id: SecureHash): Boolean
Checks whether an attachment with the given hash is stored on the node. |
authoriseContractUpgrade |
fun authoriseContractUpgrade(state: StateAndRef<*>, upgradedContractClass: Class<out UpgradedContract<*, *>>): Unit
Authorise a contract state upgrade. This will store the upgrade authorisation in the vault, and will be queried by ContractUpgradeFlow.Acceptor during contract upgrade process. Invoking this method indicate the node is willing to upgrade the state using the upgradedContractClass. This method will NOT initiate the upgrade process. To start the upgrade process, see ContractUpgradeFlow.Instigator. |
currentNodeTime |
fun currentNodeTime(): Instant
Returns the node's current time. |
deauthoriseContractUpgrade |
fun deauthoriseContractUpgrade(state: StateAndRef<*>): Unit
Authorise a contract state upgrade. This will remove the upgrade authorisation from the vault. |
getVaultTransactionNotes |
fun getVaultTransactionNotes(txnId: SecureHash): Iterable<String> |
networkMapUpdates |
fun networkMapUpdates(): Pair<List<NodeInfo>, Observable<MapChange>>
Returns all parties currently visible on the network with their advertised services and an observable of future updates to the network. |
nodeIdentity |
fun nodeIdentity(): NodeInfo
Returns Node's identity, assuming this will not change while the node is running. |
openAttachment |
fun openAttachment(id: SecureHash): InputStream
Download an attachment JAR by ID |
partyFromKey |
fun partyFromKey(key: CompositeKey): Party?
Returns the Party corresponding to the given key, if found. |
partyFromName |
fun partyFromName(name: String): Party?
Returns the Party with the given name as it's Party.name |
startFlowDynamic |
fun <T : Any> startFlowDynamic(logicType: Class<out FlowLogic<T>>, vararg args: Any?): FlowHandle<T>
Start the given flow with the given arguments, returning an Observable with a single observation of the result of running the flow. |
stateMachineRecordedTransactionMapping |
fun stateMachineRecordedTransactionMapping(): Pair<List<StateMachineTransactionMapping>, Observable<StateMachineTransactionMapping>>
Returns a snapshot list of existing state machine id - recorded transaction hash mappings, and a stream of future such mappings as well. |
stateMachinesAndUpdates |
fun stateMachinesAndUpdates(): Pair<List<StateMachineInfo>, Observable<StateMachineUpdate>>
Returns a pair of currently in-progress state machine infos and an observable of future state machine adds/removes. |
uploadAttachment |
fun uploadAttachment(jar: InputStream): SecureHash
Uploads a jar to the node, returns it's hash. |
uploadFile |
fun uploadFile(dataType: String, name: String?, file: InputStream): String |
vaultAndUpdates |
fun vaultAndUpdates(): Pair<List<StateAndRef<ContractState>>, Observable<Update>>
Returns a pair of head states in the vault and an observable of future updates to the vault. |
verifiedTransactions |
fun verifiedTransactions(): Pair<List<SignedTransaction>, Observable<SignedTransaction>>
Returns a pair of all recorded transactions and an observable of future recorded ones. |
waitUntilRegisteredWithNetworkMap |
fun waitUntilRegisteredWithNetworkMap(): ListenableFuture<Unit>
Returns a ListenableFuture which completes when the node has registered wih the network map service. It can also complete with an exception if it is unable to. |
startFlow |
fun <T : Any, R : FlowLogic<T>> CordaRPCOps.startFlow(flowConstructor: () -> R): FlowHandle<T>
These allow type safe invocations of flows from Kotlin, e.g.: fun <T : Any, A, R : FlowLogic<T>> CordaRPCOps.startFlow(flowConstructor: (A) -> R, arg0: A): FlowHandle<T> fun <T : Any, A, B, R : FlowLogic<T>> CordaRPCOps.startFlow(flowConstructor: (A, B) -> R, arg0: A, arg1: B): FlowHandle<T> fun <T : Any, A, B, C, R : FlowLogic<T>> CordaRPCOps.startFlow(flowConstructor: (A, B, C) -> R, arg0: A, arg1: B, arg2: C): FlowHandle<T> fun <T : Any, A, B, C, D, R : FlowLogic<T>> CordaRPCOps.startFlow(flowConstructor: (A, B, C, D) -> R, arg0: A, arg1: B, arg2: C, arg3: D): FlowHandle<T> |
