FlowException

open class FlowException : Exception

Exception which can be thrown by a FlowLogic at any point in its logic to unexpectedly bring it to a permanent end. The exception will propagate to all counterparty flows and will be thrown on their end the next time they wait on a FlowLogic.receive or FlowLogic.sendAndReceive. Any flow which no longer needs to do a receive, or has already ended, will not receive the exception (if this is required then have them wait for a confirmation message).

FlowException (or a subclass) can be a valid expected response from a flow, particularly ones which act as a service. It is recommended a FlowLogic document the FlowException types it can throw.
