State transition from any state

[Azatey]

How do I configure transition to some state when trigger event occurs regardless of the current state? The only way of doing that currently is basically calling .Permit(...) for all configured states, which might be too many lines of code if you have quite a few states defined.

You could use reflection:

public static class StateMachineExtension
{
    public static void PermitForAll<TState, TTrigger>(this StateMachine<TState, TTrigger> stm, TTrigger trigger, TState destination)
    {
        var info = stm.GetInfo();
        var states = info.States;
        foreach (Stateless.Reflection.StateInfo? item in states)
        {
            TState state = (TState)item.UnderlyingState;
            var config = stm.Configure(state);
            if (state.Equals(destination))
            {
                config.PermitReentry(trigger);
            }
            else
            {
                config.Permit(trigger, destination);
            }
        }
    }
}
