Jcouls29/dynamic - Githubissues

Jcouls29 commented 3 years ago

Due to a need for a more dynamic setup of workflow, a static method was added to AutomatonymousStateMachine to allow for the builder pattern. New interfaces were created and all current tests were copied and converted to the builder pattern to ensure everything was up to spec.

The general principle is that, by using the builder pattern, anyone can build a system (or framework) on top of this library where the need to build the workflow within the constructor isn't ideal. By allowing the states and events to live outside of the workflow, allows for more flexibility for these type of use cases, especially in a dynamic workflow situation where configurable workflows may be necessary.

Open to any thoughts on this approach.

Example Usage

State Waiting;
Event Start;
Event First;
Event Second;
Event Third;

AutomatonymousStateMachine<Instance>
    .Build(builder => builder
        .State("Waiting", out Waiting)
        .Event("Start", out Start)
        .Event("First", out First)
        .Event("Second", out Second)
        .Event("Third", out Third)
        .Initially()
            .When(Start, b => b.TransitionTo(Waiting))
        .During(Waiting)
            .When(First, b => b.Then(context => { context.Instance.CalledAfterAll = false; }))
            .When(Second, b => b.Then(context => { context.Instance.CalledAfterAll = false; }))
        .CompositeEvent(Third, b => b.CompositeStatus, First, Second)
        .During(Waiting)
            .When(Third, b => b
                .Then(context =>
                {
                    context.Instance.Called = true;
                    context.Instance.CalledAfterAll = true;
                })
                .Finalize()
            )

    );
