Condor.Visitor.Generator 0.0.3

Condor.Visitor.Generator

This generator help developper to generate interfaces/classes responding to the visitor pattern.

In assembly named shared, referencing assembly named Contracts, the Contracts.Abstractions.MyBaseEvent is used to generated the visitor. Derived types are discovered by the generator using the AutoAcceptorAttribute<>, it will find Contracts.MyItemCreated, Contracts.MyItemChanged, Contracts.MyITemDeleted types.

Actually, derived types cannot ordereds in the VisitREdirect method, please be aware of the behavior when using the generation of the VisitRedirect method.

namespace Shared.Visitors;

[Visitor]
[AutoAcceptor<MyBaseEvent>(AssemblyPattern = "Contracts.*", Accept = AcceptedKind.Concrete, AddVisitRedirect = true)]
[GenerateDefault(Options = OptionsDefault.AsbtractPartial, VisitOptions = VisitOptions.AbstractVisit)]
public partial interface IAppEventVisitor<in TArgs> { }

will generate :

// <auto-generated>

namespace Shared.Visitors
{
    public partial interface IAppEventVisitor<in TArgs>
    {
        void VisitRedirect(Contracts.Abstractions.MyBaseEvent element, TArgs args);
        void Visit(Contracts.MyItemChanged element, TArgs args);
        void Visit(Contracts.MyItemCreated element, TArgs args);
        void Visit(Contracts.MyItemDeleted element, TArgs args);
    }
    public abstract partial class DefaultAppEventVisitor<TArgs> : IAppEventVisitor<TArgs>
    {
        public virtual void VisitRedirect(Contracts.Abstractions.MyBaseEvent element, TArgs args)
        {
            switch (element)
            {
                case Contracts.MyItemChanged x:
                    Visit(x, args);
                    break;
                case Contracts.MyItemCreated x:
                    Visit(x, args);
                    break;
                case Contracts.MyItemDeleted x:
                    Visit(x, args);
                    break;
                default:
                    throw new System.NotSupportedException();
            }
        }
        public abstract void Visit(Contracts.MyItemChanged element, TArgs args);
        public abstract void Visit(Contracts.MyItemCreated element, TArgs args);
        public abstract void Visit(Contracts.MyItemDeleted element, TArgs args);
