# PluginServiceHub

`interface PluginServiceHub : ServiceHub`

A service hub to be used by the CordaPluginRegistry

### Inherited Properties

clock | `abstract val clock: Clock`
identityService | `abstract val identityService: IdentityService`
keyManagementService | `abstract val keyManagementService: KeyManagementService`
legalIdentityKey | `open val legalIdentityKey: KeyPair` Helper property to shorten code for fetching the Nodes KeyPair associated with the public legalIdentity Party from the key management service. Typical use is during signing in flows and for unit test signing.
myInfo | `abstract val myInfo: NodeInfo`
networkMapCache | `abstract val networkMapCache: NetworkMapCache`
networkService | `abstract val networkService: MessagingService`
notaryIdentityKey | `open val notaryIdentityKey: KeyPair` Helper property to shorten code for fetching the Nodes KeyPair associated with the public notaryIdentity Party from the key management service. It is assumed that this is only used in contexts where the Node knows it is hosting a Notary Service. Otherwise, it will throw an IllegalArgumentException. Typical use is during signing in flows and for unit test signing.
schedulerService | `abstract val schedulerService: SchedulerService`
storageService | `abstract val storageService: StorageService`
vaultService | `abstract val vaultService: VaultService`

### Functions

getFlowFactory | `abstract fun getFlowFactory(markerClass: Class<*>): (Party) -> FlowLogic<*>` Return the flow factory that has been registered with markerClass, or null if no factory is found.
registerFlowInitiator | `abstract fun registerFlowInitiator(markerClass: KClass<*>, flowFactory: (Party) -> FlowLogic<*>): Unit` Register the flow factory we wish to use when a initiating party attempts to communicate with us. The registration is done against a marker KClass which is sent in the session handshake by the other party. If this marker class has been registered then the corresponding factory will be used to create the flow which will communicate with the other side. If there is no mapping then the session attempt is rejected.

### Inherited Functions

invokeFlowAsync | `abstract fun <T : Any> invokeFlowAsync(logicType: Class<out FlowLogic<T>>, vararg args: Any?): FlowStateMachine<T>` Will check logicType and args against a whitelist and if acceptable then construct and initiate the flow. Note that you must be on the server thread to call this method.
loadState | `open fun loadState(stateRef: StateRef): TransactionState<*>` Given a StateRef loads the referenced transaction and looks up the specified output ContractState.
recordTransactions | `abstract fun recordTransactions(txs: Iterable<SignedTransaction>): Unit` Given a list of SignedTransactions, writes them to the local storage for validated transactions and then sends them to the vault for further processing.
toStateAndRef | `open fun <T : ContractState> toStateAndRef(ref: StateRef): StateAndRef<T>` Given a StateRef loads the referenced transaction and returns a StateAndRef

### Extension Functions

fillWithSomeTestCash | `fun ServiceHub.fillWithSomeTestCash(howMuch: Amount<Currency>, outputNotary: Party = DUMMY_NOTARY, atLeastThisManyStates: Int = 3, atMostThisManyStates: Int = 10, rng: Random = Random(), ref: OpaqueBytes = OpaqueBytes(ByteArray(1, { 1 })), ownedBy: CompositeKey? = null, issuedBy: PartyAndReference = DUMMY_CASH_ISSUER, issuerKey: KeyPair = DUMMY_CASH_ISSUER_KEY): Vault` Creates a random set of between (by default) 3 and 10 cash states that add up to the given amount and adds them to the vault. This is intended for unit tests. The cash is issued by DUMMY_CASH_ISSUER and owned by the legal identity key from the storage service.
recordTransactions | `fun ServiceHub.recordTransactions(vararg txs: SignedTransaction): Unit` Given some SignedTransactions, writes them to the local storage for validated transactions and then sends them to the vault for further processing.

### Inheritors

ServiceHubInternal | `abstract class ServiceHubInternal : PluginServiceHub`
