data class LedgerTransaction : NamedByHash
A LedgerTransaction wraps the data needed to calculate one or more successor states from a set of input states. It is the first step after extraction from a WireTransaction. The signatures at this point have been lined up with the commands from the wire, and verified/looked up.

LedgerTransaction(inputs: List<StateAndRef<*>>, outputs: List<TransactionState<*>>, commands: List<AuthenticatedObject<CommandData>>, attachments: List<Attachment>, id: SecureHash, notary: Party?, signers: List<PublicKey>, timestamp: Timestamp?, type: TransactionType) A LedgerTransaction wraps the data needed to calculate one or more successor states from a set of input states. It is the first step after extraction from a WireTransaction. The signatures at this point have been lined up with the commands from the wire, and verified/looked up. |
attachments |
val attachments: List<Attachment> A list of Attachment objects identified by the transaction that are needed for this transaction to verify. |
commands |
val commands: List<AuthenticatedObject<CommandData>> Arbitrary data passed to the program of each input state. |
id |
val id: SecureHash The hash of the original serialised WireTransaction. |
inputs |
val inputs: List<StateAndRef<*>> The input states which will be consumed/invalidated by the execution of this transaction. |
notary |
val notary: Party? The notary for this party, may be null for transactions with no notary. |
outputs |
val outputs: List<TransactionState<*>> The states that will be generated by the execution of this transaction. |
signers |
val signers: List<PublicKey> The notary key and the command keys together: a signed transaction must provide signatures for all of these. |
timestamp |
val timestamp: Timestamp? |
type |
val type: TransactionType |
outRef |
fun <T : ContractState> outRef(index: Int): StateAndRef<T> |
toTransactionForContract |
fun toTransactionForContract(): TransactionForContract Strips the transaction down to a form that is usable by the contract verify functions |
verify |
fun verify(): Unit Verifies this transaction and throws an exception if not valid, depending on the type. For general transactions: |
