DummyContract

class DummyContract : Contract


Types

Commands interface Commands : CommandData
MultiOwnerState 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.

SingleOwnerState data class SingleOwnerState : OwnableState, State
State interface State : ContractState

Constructors

<init> DummyContract()

Properties

legalContractReference val legalContractReference: SecureHash

Unparsed reference to the natural language contract that this code is supposed to express (usually a hash of the contracts contents).

Functions

generateInitial fun generateInitial(owner: PartyAndReference, magicNumber: Int, notary: Party): TransactionBuilder
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 theres 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.
