Class WireTransaction

BaseTransaction

net.corda.core.transactions.WireTransaction

All Implemented Interfaces:

NamedByHash

public class WireTransaction
extends BaseTransaction

A transaction ready for serialisation, without any signatures attached. A WireTransaction is usually wrapped by a class SignedTransaction that carries the signatures over this payload. The hash of the wire transaction is the identity of the transaction, that is, it's possible for two class SignedTransactions with different sets of signatures to have the same identity hash.

A transaction ready for serialisation, without any signatures attached. A WireTransaction is usually wrapped by a class SignedTransaction that carries the signatures over this payload. The hash of the wire transaction is the identity of the transaction, that is, it's possible for two class SignedTransactions with different sets of signatures to have the same identity hash.

Parameters:

inputs - Pointers to the input states on the ledger,identified by(tx identity hash,output index).

attachments - Hashes of the ZIP/JAR files that are needed to interpret the contents of this wire transaction.

commands - Ordered list of(interface CommandData,PublicKey)pairs that instruct the contracts what to do.

outRef

public <T extends ContractState> StateAndRef<T> outRef(int index)

Returns a class StateAndRef for the given output index.

See Also:

class StateAndRef

outRef

public <T extends ContractState> StateAndRef<T> outRef(ContractState state)

Returns a class StateAndRef for the requested output state, or throws IllegalArgumentException if not found.

See Also:

class StateAndRef, IllegalArgumentException

toLedgerTransaction

public LedgerTransaction toLedgerTransaction(ServiceHub services)

Looks up identities and attachments from storage to generate a class LedgerTransaction. A transaction is expected to have been fully resolved using the resolution flow by this point.

Throws:

- if a required attachment was not found in storage.

- if an input points to a transaction not found in storage.
