Step III

Evaluate, Learner Licence Tasks

  • Edit DlProcess.kprocess and change insert the below content to change the DrivingLicense flow
 role-ref RTO("rto"), Applicant("applicant")

 flow DrivingLicense {
   document(applicantId:String, firstName:String,lastName:String,  age:Int, reviewOkay:Boolean = `false`,
       first:Int?, ^second:Int?, result:Int?,
       writtenTestPassed:Boolean = `false`)

   task ReviewApplication {
     input(firstName, lastName, age) display-id("${document.firstName} ${document.lastName}")
     output(reviewOkay)
     realizer manual(RTO) distribution(system)
   }
   task SelectQuestion {
     output(first!,^second!)
     realizer auto
   }

   task WriteTest {
     input(applicantId, first!,^second!) display-id("${document.firstName} ${document.lastName}")
     output(result!)
       realizer manual(Applicant) distribution(custom)
   }

   task IssueRegretLetter {
       input(firstName)
       realizer auto
   }
   task Evaluate {
     input(first!,^second!,result!)
     output(writtenTestPassed)
       realizer auto
   }
   task IssueLL {
     input(firstName)
       realizer auto
   }

   net DL {
     init-document(applicantId, firstName,lastName, age) having coorelation-id (applicantId)
     START out (ReviewApplication)
     connector C1 in(ReviewApplication) out select {
       case  applicationFine => `reviewOkay` => SelectQuestion
       case default => IssueRegretLetter
     }
     connector C2 in(SelectQuestion) out(WriteTest)
     connector C3 in(WriteTest) out(Evaluate)
     connector C4 in(Evaluate) out select {
       case writtenTestPassed => `writtenTestPassed` => IssueLL
       case default => IssueRegretLetter
     }
       END in any (IssueRegretLetter,IssueLL)
   }
}
  • Two task got added here one is Evaluate which checks if answer entered in WriteTest is correct, other is IssueLL which issues a leraner licence. Connector C2 checks if evaluation is fine then Learner Licence gets issued else Regret Letter task gets fired.
  • Two new tasks are auto tasks, so we need to provide the code
  • EvaluateTaskCode evaluate the written test questionand returns writtenTestPassed as output
  • Edit EvaluateTaskCode and replace execute method with the following
def execute(taskId:Id, input:Input): Output = Output(input.first + input.second == input.result)
  • Edit IssueLLTaskCode and replace execute method with the following
def execute(taskId:Id, input:Input): Output = {
    println(s"Issue LL to ${input.firstName}")
    Output()
}
  • $compile
  • $run

Execute Flow

  • Go to the browser, and localhost:9000/monitor
  • enter username and password rto/rtorto (rto user can create the flow)
  • Go to Team tab and click on + button next to the team name
  • In Create Flow page select the net DL, application Id as johndoe,and First name as Steve ,Last name as Martin and age as 24.
  • Submit will create the flow, and a review Application task (notice the task is allocated to rto)
  • Go to localhost:9000/executive to see the task allocated to rto.
  • Click on the task display as Steve Martin
  • Start the task by clicking on START button, check output Review Okay as true, and COMPLETE
  • If you check output Review Okay as false,then as a result of the Connector C1, IssueRegretLetter Task will get executed and End the flow, since the flow ends in any of the task IssueregretLetter or WriteTest.
  • Now browse localhost:9000/monitor, notice SelectQuestion auto task got completed automatically, and WriteTest task is assigned to johndoe
  • Go to localhost:9000/executive but we need to login as johndoe to complete the task,so logout, and login again in executive as johndoe/johndoe(may use a different browser)
  • WriteTest task is listed, start the task. Add the numbers First and Second and enter the Result. Click on Save and Complete.
  • Logout and login as rto/rto (If a different browser is used then come back to the previous one)
  • Connector C4 tells if right answer is entered then IssueLL task get executed, if wrong answer then IssueRegretLetter, and flow ends if one of them get triggered
  • Go to http://localhost:9000/report#/flow/search and select Flow Name as DrivingLicence from the dropdown
  • Click on search result, and see the details of the flow just got completed along with all the completed tasks.

That concludes the step three.
