鏈式生產環境裝配

標籤：class   blog   ext   get   資料   string   

鏈式生產環節裝配：

    /// <summary>    /// 資料，它會反覆接收工廠裡各個環節的加工    /// </summary>    public class DataStream    {        public string Status { get; set; }    }

 

    /// <summary>    /// 節點抽象類別，類比各種機器    /// </summary>    /// <typeparam name="T"></typeparam>    public abstract class MechineNode<T> : IMechine<T>        where T : DataStream, new()    {        public IMechine<T> Next { get; set; }        public T Data { get; set; }                 public abstract IMechine<T> Execute();                public IMechine<T> Append(IMechine<T> next)         {            this.Next = next;            next.Data = this.Data;            return next;        }    }

 

    /// <summary>    /// 機器節點1    /// </summary>    /// <typeparam name="T"></typeparam>    public sealed class Mechine1<T> : MechineNode<T>        where T : DataStream, new()    {         public override IMechine<T> Execute()        {            this.Data.Status = "updated by mechine 1";            return this;        }    }

 

    /// <summary>    /// 機器節點2    /// </summary>    /// <typeparam name="T"></typeparam>    public sealed class Mechine2<T> : MechineNode<T>        where T : DataStream, new()    {        public override IMechine<T> Execute()        {            this.Data.Status += ",updated by mechine 2";            return this;        }    }

 

下面是應用：

            DataStream data = new DataStream();            IMechine<DataStream> mnode = new Mechine1<DataStream>();            mnode.Data = data;            mnode.Execute()                .Append(new Mechine2<DataStream>()).Execute()                //.Append(new Mechine2<DataStream>()).Execute() //<---通過動態鏈式環節，自由組合各台機器的裝配順序                ;
