public static class NotaryFlow.Client
extends FlowLogic
A flow to be used by a party for obtaining signature(s) from a NotaryService ascertaining the transaction timestamp is correct and none of its inputs have been used in another completed transaction.
In case of a single-node or Raft notary, the flow will return a single signature. For the BFT notary multiple signatures will be returned – one from each replica that accepted the input state commit.

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.

Override this to provide a

helpful with the progress reports. If this flow is invoked as a subflow of another, then the
tracker will be made a child of the current step in the parent. If it's null, this flow doesn't track
progress. |
