class TransactionBuilderA TransactionBuilder is a transaction class thats mutable (unlike the others which are all immutable). It is intended to be passed around contracts that may edit it by adding new states/commands or modifying the existing set. Then once the states and commands are right, this class can be used as a holding bucket to gather signatures from multiple parties.

fun addSignatureUnchecked(sig: WithKey): UnitAdds the signature directly to the transaction, without checking it for validity. |

fun attachments(): List<SecureHash> |
| checkAndAddSignature |
fun checkAndAddSignature(sig: WithKey): UnitChecks that the given signature matches one of the commands and that it is a correct signature over the tx, then adds it. |

fun checkSignature(sig: WithKey): UnitChecks that the given signature matches one of the commands and that it is a correct signature over the tx. |

| setTime |
fun setTime(time: Instant, authority: Party, timeTolerance: Duration): UnitPlaces a TimestampCommand in this transaction, removing any existing command if there is one. The command requires a signature from the Notary service, which acts as a Timestamp Authority. The signature can be obtained using NotaryProtocol. |
