interface ServiceHub
A service hub simply vends references to the other services a node has. Some of those services may be missing or mocked out. This class is useful to pass to chunks of pluggable code that might have need of many different kinds of functionality and you dont want to hard-code which types in the interface.
Any services exposed to protocols (public view) need to implement SerializeAsToken or similar to avoid their internal state from being serialized in checkpoints.

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 wallet for further processing. open fun recordTransactions(vararg txs: SignedTransaction): <ERROR CLASS> Given some SignedTransactions, writes them to the local storage for validated transactions and then sends them to the wallet for further processing. |
verifyTransaction |
open fun verifyTransaction(ltx: LedgerTransaction): Unit Given a LedgerTransaction, looks up all its dependencies in the local database, uses the identity service to map the SignedTransactions the DB gives back into LedgerTransactions, and then runs the smart contracts for the transaction. If no exception is thrown, the transaction is valid. |

fun ServiceHub.fillWithSomeTestCash(howMuch: Amount<Currency>, notary: Party = DUMMY_NOTARY, atLeastThisManyStates: Int = 3, atMostThisManyStates: Int = 10, rng: Random = Random(), ref: OpaqueBytes = OpaqueBytes(ByteArray(1, { 0 }))): Wallet 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 wallet. This is intended for unit tests. |
