SnapshotManager

SnapshotManager 是一个通用快照与差异管理工具，用于保存对象状态并计算对象差异（Diff），支持复杂对象结构，如二维数组。

核心接口与类

  • IDiff<T> 对象实现自定义差异计算：

    public interface IDiff<T>
{
    DiffNode Diff(T oldValue, T newValue);
}

  • ElementBase 通用基类，实现字段级自动 Diff：

    public abstract class ElementBase : IDiff<ElementBase>
{
    public abstract ElementBase DeepClone();
    public virtual DiffNode Diff(ElementBase oldValue, ElementBase newValue) { ... }
}

  • ElementArraySnapshot 保存二维列表快照：

    public class ElementArraySnapshot : Snapshot<List<List<ElementBase>>>
{
    public ElementArraySnapshot(string name, string desc, List<List<ElementBase>> src)
        : base(name, desc, DeepClone2D(src)) { }
    private static List<List<ElementBase>> DeepClone2D(List<List<ElementBase>> src) => 
        src.Select(row => row.Select(e => e?.DeepClone()).ToList()).ToList();
}

  • SnapshotManager<T> 管理快照并计算差异：

    var manager = new SnapshotManager<List<List<ElementBase>>>();
manager.AddSnapshot("s1", snapshot1);
manager.AddSnapshot("s2", snapshot2);
var diff = manager.CompareSnapshots("s1", "s2");

使用示例

var elements = new List<List<ElementBase>> { new() { new MyElement { Value = 1 } } };
var snapshot1 = new ElementArraySnapshot("s1", "初始", elements);

// 修改后快照
elements[0][0] = new MyElement { Value = 10 };
var snapshot2 = new ElementArraySnapshot("s2", "修改后", elements);

// 管理与对比
var manager = new SnapshotManager<List<List<ElementBase>>>();
manager.AddSnapshot("s1", snapshot1);
manager.AddSnapshot("s2", snapshot2);
var diff = manager.CompareSnapshots("s1", "s2");
Console.WriteLine(diff);
