API: RPC operations

The node's owner interacts with the node solely via remote procedure calls (RPC). The node's owner does not have access to the node's ServiceHub.

The key RPC operations exposed by the node are:

CordaRPCOps.vaultQueryBy
- Extract states from the node's vault based on a query criteria
CordaRPCOps.vaultTrackBy
- As above, but also returns an observable of future states matching the query
CordaRPCOps.verifiedTransactions
- Extract all transactions from the node's local storage, as well as an observable of all future transactions
CordaRPCOps.networkMapUpdates
- A list of network nodes, and an observable of changes to the network map
CordaRPCOps.registeredFlows
- See a list of registered flows on the node
CordaRPCOps.startFlowDynamic
- Start one of the node's registered flows
CordaRPCOps.startTrackedFlowDynamic
- As above, but also returns a progress handle for the flow
CordaRPCOps.nodeIdentity
- Returns the node's identity
CordaRPCOps.currentNodeTime
- Returns the node's current time
CordaRPCOps.partyFromKey/CordaRPCOps.partyFromX500Name
- Retrieves a party on the network based on a public key or X500 name
CordaRPCOps.uploadAttachment/CordaRPCOps.openAttachment/CordaRPCOps.attachmentExists
