data class MultiOwnerState : ContractState, State
Alternative state with multiple owners. This exists primarily to provide a dummy state with multiple participants, and could in theory be merged with SingleOwnerState by putting the additional participants in a different field, however this is a good example of a contract with multiple states. |

DummyContract(legalContractReference: SecureHash = SecureHash.sha256("")) |
legalContractReference |
val legalContractReference: SecureHash
Unparsed reference to the natural language contract that this code is supposed to express (usually a hash of the contract's contents). |
verify |
fun verify(tx: TransactionForContract): Unit
Takes an object that represents a state transition, and ensures the inputs/outputs/commands make sense. Must throw an exception if there's a problem that should prevent state transition. Takes a single object rather than an argument so that additional data can be added without breaking binary compatibility with existing contract code. |
