FlowMessaging

FlowMessaging allows a flow to initiate and communicate with one or more 3rd party flows.

The platform will provide an instance of FlowMessaging to flows via property injection.

A Flow can initiate one or more flows other counterparties within the network, when a new flow is initiated a FlowSession is created. The FlowSession represents the connection to an initiated flow and can be used to send and receive data between the two flows.

Example usage:

• Kotlin:

  
  class MyFlow : ClientStartableFlow {
     
     lateinit var flowMessaging: FlowMessaging
  
     override fun call(requestBody: RestRequestBody): String {
         val counterparty = parse("CN=Alice, O=Alice Corp, L=LDN, C=GB")
  
         val session = flowMessaging.initiateFlow(counterparty)
  
         val result = session.sendAndReceive<String>("hello")
  
         session.close()
  
         return result
     }
   }
