Stateless

Create state machines and lightweight state machine-based workflows directly in .NET code:

var phoneCall = new StateMachine<State, Trigger>(State.OffHook);

phoneCall.Configure(State.OffHook)
    .Permit(Trigger.CallDialled, State.Ringing);

phoneCall.Configure(State.Connected)
    .OnEntry(t => StartCallTimer())
    .OnExit(t => StopCallTimer())
    .InternalTransition(Trigger.MuteMicrophone, t => OnMute())
    .InternalTransition(Trigger.UnmuteMicrophone, t => OnUnmute())
    .InternalTransition<int>(_setVolumeTrigger, (volume, t) => OnSetVolume(volume))
    .Permit(Trigger.LeftMessage, State.OffHook)
    .Permit(Trigger.PlacedOnHold, State.OnHold);

// ...

phoneCall.Fire(Trigger.CallDialled);
Assert.AreEqual(State.Ringing, phoneCall.State);

This project, as well as the example above, was inspired by Simple State Machine (Archived).

Features

Most standard state machine constructs are supported:

  • Generic support for states and triggers of any .NET type (numbers, strings, enums, etc.)
  • Hierarchical states
  • Entry/exit actions for states
  • Guard clauses to support conditional transitions
  • Introspection

Some useful extensions are also provided:

  • Ability to store state externally (for example, in a property tracked by an ORM)
  • Parameterised triggers
  • Reentrant states
  • Export to DOT graph

Documentation

For guidance on how to use Stateles, the project README file contains documentation and code examples. The source repository also includes a few example projects.
