AbstractCashFlow |
abstract class AbstractCashFlow : FlowLogic<SignedTransaction>
Initiates a flow that produces an Issue/Move or Exit Cash transaction. |
AbstractStateReplacementFlow |
abstract class AbstractStateReplacementFlow
Abstract flow to be used for replacing one state with another, for example when changing the notary of a state. Notably this requires a one to one replacement of states, states cannot be split, merged or issued as part of these flows. |
BroadcastTransactionFlow |
class BroadcastTransactionFlow : FlowLogic<Unit>
Notify the specified parties about a transaction. The remote peers will download this transaction and its dependency graph, verifying them all. The flow returns when all peers have acknowledged the transactions as valid. Normally you wouldn't use this directly, it would be called via FinalityFlow. |
CashExitFlow |
class CashExitFlow : AbstractCashFlow
Initiates a flow that produces an cash exit transaction. |
CashFlowCommand |
sealed class CashFlowCommand
A command to initiate the Cash flow with. |
CashIssueFlow |
class CashIssueFlow : AbstractCashFlow
Initiates a flow that produces cash issuance transaction. |
CashPaymentFlow |
open class CashPaymentFlow : AbstractCashFlow
Initiates a flow that produces an cash move transaction. |
ContractUpgradeFlow |
object ContractUpgradeFlow
A flow to be used for upgrading state objects of an old contract to a new contract. |
FetchAttachmentsFlow |
class FetchAttachmentsFlow : FetchDataFlow<Attachment, ByteArray>
Given a set of hashes either loads from from local storage or requests them from the other peer. Downloaded attachments are saved to local storage automatically. |
FetchDataFlow |
abstract class FetchDataFlow<T : NamedByHash, in W : Any> : FlowLogic<Result<T>>
An abstract flow for fetching typed data from a remote peer. |
FetchTransactionsFlow |
class FetchTransactionsFlow : FetchDataFlow<SignedTransaction, SignedTransaction>
Given a set of tx hashes (IDs), either loads them from local disk or asks the remote peer to provide them. |
FinalityFlow |
class FinalityFlow : FlowLogic<List<SignedTransaction>>
Verifies the given transactions, then sends them to the named notaries. If the notary agrees that the transactions are acceptable then they are from that point onwards committed to the ledger, and will be written through to the vault. Additionally they will be distributed to the parties reflected in the participants list of the states. |
IssuerFlow |
object IssuerFlow
This flow enables a client to request issuance of some FungibleAsset from a server acting as an issuer (see Issued) of FungibleAssets. |
NonValidatingNotaryFlow |
class NonValidatingNotaryFlow : Service |
NotaryChangeFlow |
object NotaryChangeFlow : AbstractStateReplacementFlow
A flow to be used for changing a state's Notary. This is required since all input states to a transaction must point to the same notary. |
NotaryError |
sealed class NotaryError |
NotaryFlow |
object NotaryFlow |
ResolveTransactionsFlow |
class ResolveTransactionsFlow : FlowLogic<List<LedgerTransaction>>
This flow is used to verify the validity of a transaction by recursively checking the validity of all the dependencies. Once a transaction is checked it's inserted into local storage so it can be relayed and won't be checked again. |
ServiceRequestMessage |
interface ServiceRequestMessage
Abstract superclass for request messages sent to services which expect a reply. |
TwoPartyDealFlow |
object TwoPartyDealFlow
Classes for manipulating a two party deal or agreement. |
TwoPartyTradeFlow |
object TwoPartyTradeFlow
This asset trading flow implements a "delivery vs payment" type swap. It has two parties (B and S for buyer and seller) and the following steps: |
ValidatingNotaryFlow |
class ValidatingNotaryFlow : Service
A notary commit flow that makes sure a given transaction is valid before committing it. This does mean that the calling party has to reveal the whole transaction history; however, we avoid complex conflict resolution logic where a party has its input states "blocked" by a transaction from another party, and needs to establish whether that transaction was indeed valid. |
CashException |
class CashException : FlowException |
NotaryException |
class NotaryException : FlowException |
StateReplacementException |
open class StateReplacementException : FlowException |
sendRequest |
fun <R : Any> MessagingService.sendRequest(topic: String, request: ServiceRequestMessage, target: MessageRecipients): ListenableFuture<R>
Sends a ServiceRequestMessage to target and returns a ListenableFuture of the response. |
