interface CordaRPCOps : RPCOps
RPC operations that the node exposes to clients.
networkParameters |
Returns the network parameters the node is operating under. abstract val networkParameters: NetworkParameters |
acceptNewNetworkParameters |
Accept network parameters with given hash, hash is obtained through networkParametersFeed method. Information is sent back to the zone operator that the node accepted the parameters update - this process cannot be undone. Only parameters that are scheduled for update can be accepted, if different hash is provided this method will fail. Note: This operation may be restricted only to node administrators. abstract fun acceptNewNetworkParameters(parametersHash: SecureHash): Unit |
addVaultTransactionNote |
Add note(s) to an existing Vault transaction. abstract fun addVaultTransactionNote(txnId: SecureHash, txnNote: String): Unit |
attachmentExists |
Checks whether an attachment with the given hash is stored on the node. abstract fun attachmentExists(id: SecureHash): Boolean |
clearNetworkMapCache |
Clear all network map data from local node cache. Notice that after invoking this method your node will lose
network map data and effectively won't be able to start any flow with the peers until network map is downloaded
again on next poll - from abstract fun clearNetworkMapCache(): Unit |
currentNodeTime |
Returns the node's current time. abstract fun currentNodeTime(): Instant |
finishedFlowsWithClientIds |
Returns all finished flows that were started with a client ID for which the client ID mapping has not been removed. This version only returns the client ids for flows started by the same user currently calling finishedFlowsWithClientIds. abstract fun finishedFlowsWithClientIds(): Map<String, Boolean> |
finishedFlowsWithClientIdsAsAdmin |
Returns all finished flows that were started with a client id by all RPC users for which the client ID mapping has not been removed. abstract fun finishedFlowsWithClientIdsAsAdmin(): Map<String, Boolean> |
getVaultTransactionNotes |
Retrieve existing note(s) for a given Vault transaction. abstract fun getVaultTransactionNotes(txnId: SecureHash): Iterable<String> |
isFlowsDrainingModeEnabled |
Returns whether the flows draining mode is enabled. abstract fun isFlowsDrainingModeEnabled(): Boolean |
isWaitingForShutdown |
Returns whether the node is waiting for pending flows to complete before shutting down. Disabling draining mode cancels this state. abstract fun isWaitingForShutdown(): Boolean |

Returns all parties currently visible on the network with their advertised services. abstract fun networkMapSnapshot(): List<NodeInfo> |
networkParametersFeed |

openAttachment |
Download an attachment JAR by ID. abstract fun openAttachment(id: SecureHash): InputStream |
partiesFromName |
Returns a list of candidate matches for a given string, with optional fuzzy(ish) matching. Fuzzy matching may get smarter with time e.g. to correct spelling errors, so you should not hard-code indexes into the results but rather show them via a user interface and let the user pick the one they wanted. abstract fun partiesFromName(query: String, exactMatch: Boolean): Set<Party> |
partyFromKey |
Returns the Party corresponding to the given key, if found. abstract fun partyFromKey(key: PublicKey): Party? |

Poll network map server if available for the network map. Notice that you need to have abstract fun refreshNetworkMapCache(): Unit |
registeredFlows |
Enumerates the class names of the flows that this node knows about. abstract fun registeredFlows(): List<String> |
removeClientId |

removeClientIdAsAdmin |
Removes a flow's clientId to result/ exception mapping. If the mapping is of a running flow, then the mapping will not get removed. This version can be called for all client ids, ignoring which user originally started a flow with clientId. abstract fun removeClientIdAsAdmin(clientId: String): Boolean |
setFlowsDrainingModeEnabled |
Sets the value of the node's flows draining mode. If this mode is enabled, the node will reject new flows through RPC, ignore scheduled flows, and do not process initial session messages, meaning that P2P counterparties will not be able to initiate new flows involving the node. abstract fun setFlowsDrainingModeEnabled(enabled: Boolean): Unit |
shutdown |
Shuts the node down. Returns immediately. This does not wait for flows to be completed. abstract fun shutdown(): Unit |
startFlowDynamic |
