ResponderFlow

All Implemented Interfaces:

net.corda.v5.application.flows.Flow
```
public interface ResponderFlow
 implements Flow
                    
```
ResponderFlow is a Flow that is started by receiving a message from a peer.
A ResponderFlow must be annotated with InitiatedBy to be invoked by a session message. If both these requirements are met, then the flow will be invoked via call which takes a FlowSession. This session is created by the platform and communicates with the party that initiated the session.
Flows implementing this interface must have a no-arg constructor. The flow invocation will fail if this constructor does not exist.

@Suspendable() abstract void call(@NotNull() FlowSession session)
```
    The business logic for the flow should be written here.
    This is equivalent to the call method for a normal flow. This version is invoked when the flow is started via an incoming session init event, via a counterparty calling initiateFlow.
    
    Parameters:
    
    session - The session opened by the counterparty.
