ValidatingNotaryFlow

class ValidatingNotaryFlow : Service

A notary commit flow that makes sure a given transaction is valid before committing it. This does mean that the calling party has to reveal the whole transaction history; however, we avoid complex conflict resolution logic where a party has its input states "blocked" by a transaction from another party, and needs to establish whether that transaction was indeed valid.

Functions

receiveAndVerifyTx fun receiveAndVerifyTx(): TransactionParts

The received transaction is checked for contract-validity, which requires fully resolving it into a TransactionForVerification, for which the caller also has to to reveal the whole transaction dependency chain.

Inherited Functions

call open fun call(): Void?

This is where you fill out your business logic. The returned object will usually be ignored, but can be helpful if this flow is meant to be used as a subflow.
