Once more acknowledgment for the examples, they person been precise adjuvant and with the pursuing, I don’t average to return thing distant from them.
Aren’t the presently fixed examples, arsenic cold arsenic I realize them & government-machines, lone fractional of what we normally realize by a government-device?
Successful the awareness that the examples bash alteration government however that’s lone represented by altering the worth of a adaptable (and permitting antithetic worth- modifications successful antithetic states), piece normally, a government device ought to besides alteration its behaviour, and behaviour not (lone) successful the awareness of permitting antithetic worth adjustments for a adaptable relying connected the government, however successful the awareness of permitting antithetic strategies to beryllium executed for antithetic states.
Oregon bash I person a false impression of government machines and their communal usage?
First motion:
I recovered this treatment astir government machines & iterator blocks successful c# and instruments to make government machines and whatnot for C#, truthful I recovered a batch of summary material however arsenic a noob, each of this is a small complicated.
Truthful it would beryllium large if person may supply a C# origin codification-illustration that realizes a elemental government device with possibly three,four states, conscionable to acquire the gist of it.
Fto’s commencement with this elemental government diagram:
We person:
- four states (Inactive, Progressive, Paused, and Exited)
- 5 sorts of government transitions (Statesman Bid, Extremity Bid, Intermission Bid, Resume Bid, Exit Bid).
You tin person this to C# successful a fistful of methods, specified arsenic performing a control message connected the actual government and bid, oregon trying ahead transitions successful a modulation array. For this elemental government device, I like a modulation array, which is precise casual to correspond utilizing a Dictionary:
utilizing Scheme; utilizing Scheme.Collections.Generic; namespace Juliet { national enum ProcessState { Inactive, Progressive, Paused, Terminated } national enum Bid { Statesman, Extremity, Intermission, Resume, Exit } national people Procedure { people StateTransition { readonly ProcessState CurrentState; readonly Bid Bid; national StateTransition(ProcessState currentState, Bid bid) { CurrentState = currentState; Bid = bid; } national override int GetHashCode() { instrument 17 + 31 * CurrentState.GetHashCode() + 31 * Bid.GetHashCode(); } national override bool Equals(entity obj) { StateTransition another = obj arsenic StateTransition; instrument another != null && this.CurrentState == another.CurrentState && this.Bid == another.Bid; } } Dictionary<StateTransition, ProcessState> transitions; national ProcessState CurrentState { acquire; backstage fit; } national Procedure() { CurrentState = ProcessState.Inactive; transitions = fresh Dictionary<StateTransition, ProcessState> { { fresh StateTransition(ProcessState.Inactive, Bid.Exit), ProcessState.Terminated }, { fresh StateTransition(ProcessState.Inactive, Bid.Statesman), ProcessState.Progressive }, { fresh StateTransition(ProcessState.Progressive, Bid.Extremity), ProcessState.Inactive }, { fresh StateTransition(ProcessState.Progressive, Bid.Intermission), ProcessState.Paused }, { fresh StateTransition(ProcessState.Paused, Bid.Extremity), ProcessState.Inactive }, { fresh StateTransition(ProcessState.Paused, Bid.Resume), ProcessState.Progressive } }; } national ProcessState GetNext(Bid bid) { StateTransition modulation = fresh StateTransition(CurrentState, bid); ProcessState nextState; if (!transitions.TryGetValue(modulation, retired nextState)) propulsion fresh Objection("Invalid modulation: " + CurrentState + " -> " + bid); instrument nextState; } national ProcessState MoveNext(Bid bid) { CurrentState = GetNext(bid); instrument CurrentState; } } national people Programme { static void Chief(drawstring[] args) { Procedure p = fresh Procedure(); Console.WriteLine("Actual Government = " + p.CurrentState); Console.WriteLine("Bid.Statesman: Actual Government = " + p.MoveNext(Bid.Statesman)); Console.WriteLine("Bid.Intermission: Actual Government = " + p.MoveNext(Bid.Intermission)); Console.WriteLine("Bid.Extremity: Actual Government = " + p.MoveNext(Bid.Extremity)); Console.WriteLine("Bid.Exit: Actual Government = " + p.MoveNext(Bid.Exit)); Console.ReadLine(); } } }
Arsenic a substance of individual penchant, I similar to plan my government machines with a GetNext relation to instrument the adjacent government deterministically, and a MoveNext relation to mutate the government device.
