Class NotaryChangeLedgerTransaction

net.corda.core.transactions.BaseTransaction

FullTransaction

net.corda.core.transactions.NotaryChangeLedgerTransaction

All Implemented Interfaces:

NamedByHash, TransactionWithSignatures

public class NotaryChangeLedgerTransaction
extends FullTransaction
implements TransactionWithSignatures

A notary change transaction with fully resolved inputs and signatures. In contrast with a regular transaction, signatures are checked against the signers specified by input states' participants fields, so full resolution is needed for signature verification.

Method Detail

getReferences

@NotNull
public java.util.List<net.corda.core.contracts.StateAndRef> getReferences()

A list of reusable reference data states which can be referred to by other contracts in this transaction.

getOutputs

@NotNull
public java.util.List<net.corda.core.contracts.TransactionState> getOutputs()

We compute the outputs on demand by applying the notary field modification to the inputs.

getRequiredSigningKeys

@NotNull
public java.util.Set<java.security.PublicKey> getRequiredSigningKeys()

Specifies all the public keys that require signatures for the transaction to be valid.

getKeyDescriptions

@NotNull
public java.util.List<java.lang.String> getKeyDescriptions(@NotNull
                                                                    java.util.Set<? extends java.security.PublicKey> keys)

Get a human readable description of where signatures are required from, and are missing, to assist in debugging the underlying cause.

Note that the results should not be serialised, parsed or expected to remain stable between Corda versions.
