ContractUpgradeWireTransaction

Component

<init>

A special transaction for upgrading the contract of a state.

digestService

id

inputs

The inputs of this transaction, containing state references only.

legacyContractAttachmentId

networkParametersHash

Hash of the network parameters that were in force when the transaction was notarised. Null means, that the transaction was created on older version of Corda (before 4), resolution will default to initial parameters.

notary

If present, the notary for this transaction. If absent then the transaction is not notarised at all. This is intended for issuance/genesis transactions that don't consume any other states and thus can't double spend anything.

outputs

This transaction does not contain any output states, outputs can be obtained by resolving a ContractUpgradeLedgerTransaction – outputs will be calculated on demand by applying the contract upgrade operation to inputs.

privacySalt

Required for hiding components in ContractUpgradeFilteredTransaction.

references

ContractUpgradeWireTransactions should not contain reference input states.

serializedComponents

Contains all of the transaction components in serialized form. This is used for calculating the transaction id in a deterministic fashion, since re-serializing properties may result in a different byte sequence depending on the serialization context.

upgradedContractClassName

buildFilteredTransaction

Constructs a filtered transaction: the inputs, the notary party and network parameters hash are always visible, while the rest are hidden.

copy

Old version of ContractUpgradeWireTransaction.copy for sake of ABI compatibility.

resolve

Resolves input states and contract attachments, and builds a ContractUpgradeLedgerTransaction.
