The Pattern in .NET

Configuration via DSL

The configuration determines the data flow.

var config = new string[] {
    ".run -- action",
    "    action.render -- render",
    "        render.output -- .out",
    "    action.log -- log",
    "        log.store -- .out"
};

Actors

Each function represents an actor.

public class Actors
{
   public void Action(
       string data, Output<string> render,
       Output<int, string> store)
   {
       render.Invoke(data);
       Console.WriteLine(
           string.Format("{0} in Action', data));
       log.Invoke("render done");
   }

   public void Render(string data)
   {
       Console.WriteLine(
           string.Format("{0} in Render', data));
   }

   public void Store(int id, string data)
   {
       Console.WriteLine(
           string.Format("{0} and {1} in Store', id, data));
   }
}

Graph

var actors = new Actors();
var graph = new Graph(config);

graph.Actor("action", actors.Action);
graph.Actor("render", actors.Render);
graph.Actor("store", actors.Store);

Visualize

graph.Visualize();

Run the flow

graph.Run("Hello");

$ Hello in Render
$ Hello in Action
$ Hello and 1 in Store
