Extract old, deprecated v2 self-contained binary partially unpacked by the TransactionPack, and fill
addNewItems
Add one or more siblings to the contract. Note that those must be sealed before calling #seal() or #
addSignerKey
Add private key to keys contract binary to be signed with when sealed next time. It is called before
getExpiresAt
Get contract expiration time
getId
Get the id sealing self if need
getPackedTransaction
Pack the contract to the most modern .unicon format, same as TransactionPack#pack(). Uses bounded Tr
registerRole
Register new role. Name must be unique otherwise existing role will be overwritten
seal
Seal contract to binary. This call adds signatures from #getKeysToSignWith()
addSignatureToSeal
Add signature to sealed (before) contract. Do not deserializing or changing contract bytes, but will

createRevision
Create new revision to be changed, signed sealed and then ready to approve. Created "revision" contr
fromDslFile
Create contract importing its parameters with passed .yaml file. No signatures are added automatical
