Creating Tutorial.ExampleOperation

Here are the steps for creating Tutorial.ExampleOperation using VS Code - ObjectScript:

1. If you haven't already, within the source code folder in your workspace (probably named src), add a new folder named Tutorial.

2. Within the Tutorial folder, add a new file named ExampleOperation.cls.

3. Enter the following code:

   
   Class Tutorial.ExampleOperation extends Ens.BusinessOperation {
   
   Parameter INVOCATION = "Queue";
   
   Method Test(pRequest As Ens.StringRequest, Output pResponse As Ens.StringResponse) As %Status
   {
    Set pResponse=##class(Ens.StringResponse).%New()
    if (pRequest.StringValue="")
    {
      Set pResponse.StringValue="ERROR"
      Set tSC=$$$ERROR($$$GeneralError, "Test error case")
    }
    else
    {
      Set pResponse.StringValue="OK"
      Set tSC=$$$OK
    }
    $$$LOGINFO(pResponse.StringValue)
    Return tSC
    }
   }
   
   XData MessageMap {
   <MapItems>
       <MapItem MessageType="Ens.StringRequest">
           <Method>Test</Method>
       </MapItem>
   </MapItems>
   }
   
   }
