Machinery

Machinery is a minimalistic .NET library for dealing with state machines.

Usage

Implement IState<C, E, S> by your base state:

public interface IState<in TContext, in TEvent, TState>
{
    bool TryCreateNewState(TContext context, TEvent ev, out TState newState);
    void OnExiting(TContext context, TEvent ev, TState newState);
    void OnExited(TContext context, TEvent ev, TState newState);
    void OnRemain(TContext context, TEvent ev);
    void OnEntering(TContext context, TEvent ev, TState oldState);
    void OnEntered(TContext context, TEvent ev, TState oldState);
}

MyContext context = …;
MyState initialState = …;
var stateMachine = StateMachine<Event>.Create(context, initialState);

MyEvent ev = …;
_ = stateMachine.TryProcessEvent(ev);
MyState currentState = stateMachine.CurrentState;
