open class InMemoryWalletService : SingletonSerializeAsToken, WalletService
This class implements a simple, in memory wallet that tracks states that are owned by us, and also has a convenience method to auto-generate some self-issued cash states that can be used for test trading. A real wallet would persist states relevant to us into a database and once such a wallet is implemented, this scaffolding can be removed.

InMemoryWalletService(services: ServiceHub) This class implements a simple, in memory wallet that tracks states that are owned by us, and also has a convenience method to auto-generate some self-issued cash states that can be used for test trading. A real wallet would persist states relevant to us into a database and once such a wallet is implemented, this scaffolding can be removed. |
currentWallet |
open val currentWallet: Wallet Returns a read-only snapshot of the wallet at the time the call is made. Note that if you consume states or keys in this wallet, you must inform the wallet service so it can update its internal state. |
linearHeads |
open val linearHeads: Map<UniqueIdentifier, StateAndRef<LinearState>> Returns a snapshot of the heads of LinearStates. |
log |
open val log: <ERROR CLASS> |
mutex |
val mutex: ThreadBox<InnerState> |
services |
val services: ServiceHub |
updates |
open val updates: <ERROR CLASS><Update> Get a synchronous Observable of updates. When observations are pushed to the Observer, the Wallet will already incorporate the update. |
notifyAll |
open fun notifyAll(txns: Iterable<WireTransaction>): Wallet Possibly update the wallet by marking as spent states that these transactions consume, and adding any relevant new states that they create. You should only insert transactions that have been successfully verified here |
linearHeadsOfType_ |
open fun <T : LinearState> linearHeadsOfType_(stateType: Class<T>): Map<UniqueIdentifier, StateAndRef<T>> Returns the linearHeads only when the type of the state would be considered an instanceof the given type. |
notify |
open fun notify(tx: WireTransaction): Wallet Same as notifyAll but with a single transaction. |
statesForRefs |
open fun statesForRefs(refs: List<StateRef>): Map<StateRef, TransactionState<*>?> |
toToken |
open fun toToken(context: SerializeAsTokenContext): SerializationToken |
whenConsumed |
open fun whenConsumed(ref: StateRef): <ERROR CLASS><Update> Provide a Future for when a StateRef is consumed, which can be very useful in building tests. |
linearHeadsOfType |
fun <T : LinearState> WalletService.linearHeadsOfType(): <ERROR CLASS> |
NodeWalletService |
class NodeWalletService : InMemoryWalletService Currently, the node wallet service is a very simple RDBMS backed implementation. It will change significantly when we add further functionality as the design for the wallet and wallet service matures. |
