TransactionType

sealed class TransactionType

Defines transaction build & validation logic for a specific transaction type

Types

General	`class General : TransactionType` A general transaction type where transaction validity is determined by custom contract code
NotaryChange	`class NotaryChange : TransactionType` A special transaction type for reassigning a notary for a state. Validation does not involve running any contract code, it just checks that the states are unmodified apart from the notary field.

Functions

equals	`open fun equals(other: Any?): Boolean`
getRequiredSigners	`abstract fun getRequiredSigners(tx: LedgerTransaction): Set<PublicKeyTree>` Return the list of public keys that that require signatures for the transaction type. Note: the notary key is checked separately for all transactions and need not be included.
hashCode	`open fun hashCode(): <ERROR CLASS>`
verify	`fun verify(tx: LedgerTransaction): Unit` Check that the transaction is valid based on:
verifySigners	`fun verifySigners(tx: LedgerTransaction): Set<PublicKeyTree>` Check that the list of signers includes all the necessary keys
verifyTransaction	`abstract fun verifyTransaction(tx: LedgerTransaction): Unit` Implement type specific transaction validation logic
