Flexi Archive 提供了多种存档读写的操作方案，包括：

1.持有DataObject操作存档

2.对象字段与数据绑定  对象字段与数据绑定 - 简化存档流程

其中DataObject是核心，但对象字段与数据绑定的操作也极大地简化了存档流程。

对象字段与数据绑定 #

对象字段与数据绑定是Flexi Archive提供的另一种简化存档流程的操作方案。这种方式利用了数据绑定的特性，使得对象字段的变化能够自动反映到存档数据中，从而简化了存档操作。

代码示例：（ 更多绑定方式见文档 ：  对象字段与数据绑定 - 简化存档流程  ）

public class DataContainerForSave_Sample : FlexiDataContainer
    {
        public string author
        {
            get => GetMemoryValue<DataString, string>("FlexiDataSave","author");
            set => ModifyValue<DataString, string>("FlexiDataSave","author", value);
        }
        
        public int age
        {
            get => GetMemoryValue<DataInteger, int>("FlexiDataSave","age");
            set => ModifyValue<DataInteger, int>("FlexiDataSave","age", value);
        }
    
        public DataContainerForSave_Sample(IFlexiDataArchiveManager dataArchiveManager)
        {
            SetDataArchiveManager(dataArchiveManager);
        }
    }

持有DataObject操作存档 #

通过 GroupKey + DataKey 从存档系统中得到一个DataObject实例，示例：archiveManager.GetDataObject("group1", "key1"); 。

DataObject相当一个数据管理容器，我们可以从DataObject中获取到具体的数据对象。TDataWrapper idataWrapper = dataObject.GetData<TDataWrapper>();

写入数据：idataWrapper.Write(new TData());

从磁盘中读取数据：idataWrapper.DiskData

从内存中读取数据：idataWrapper.Data

目前系统已支持的数据类型：

float、double、int、long、bool、string、vector2 、vector3、vector4

object、list、array、dictionary、custom（所有自定义类型） ·····

下面重点介绍几种常用的数据类型

String #

DataWrapper：DataString

写入数据：

		private string WriteStr()
		{
			DataObject dataObject = archiveManager.GetDataObject("group1", "key1");
			DataString dataString = dataObject.GetData<DataString>();
			dataString.Write(char.ConvertFromUtf32(Random.Range(65, 123)));
			Debug.Log(string.Format($"[{Path.Combine("group1", "key1")}]: write a str ：{dataString.data}"));
			return dataString.data;
		}

读取数据：

		private string ReadStrFromDisk()
		{
			DataObject dataObject = archiveManager.GetDataObject("group1", "key1");
			DataString dataString = dataObject.GetData<DataString>();
			string str = dataString.DiskData;
			Debug.Log(string.Format($"[{Path.Combine("group1", "key1")}]: read a str from disk: {str}"));
			return str;
		}

Int32 #

DataWrapper：DataInteger

写入数据：

		private string WriteInt()
		{
			DataObject dataObject = archiveManager.GetDataObject("group2", "key1");
			DataInteger dataInteger = dataObject.GetData<DataInteger>();
			dataInteger.Write(Random.Range(0, 5));
			Debug.Log(string.Format(
				$"[{Path.Combine("group2", "key1")}]: write a number of type int {dataInteger.data}"));
			return dataInteger.data.ToString();
		}

读取数据：

		private string ReadIntFromDisk()
		{
			DataObject dataObject = archiveManager.GetDataObject("group2", "key1");
			DataInteger dataInteger = dataObject.GetData<DataInteger>();
			Debug.Log(string.Format(
				$"[{Path.Combine("group2", "key1")}]: read a int from disk  : {dataInteger.DiskData}"));
			return dataInteger.DiskData.ToString();
		}

 Vector3 #

DataWrapper：DataVector3

写入数据：

		private string WriteVector3()
		{
			DataObject dataObject = archiveManager.GetDataObject("group2", "key2");
			DataVector3 dataVector3 = dataObject.GetData<DataVector3>();
			dataVector3.Write(new Vector3(Random.Range(0, 100), Random.Range(0, 100), Random.Range(0, 100)));
			Debug.Log(string.Format($"[{Path.Combine("group2", "key2")}]: write a vector3 ：{dataVector3.data}"));
			return dataVector3.data.ToString();
		}

读取数据：

		private string ReadVector3()
		{
			DataObject dataObject = archiveManager.GetDataObject("group2", "key2");
			DataVector3 dataVector3 = dataObject.GetData<DataVector3>();
			Debug.Log(string.Format(
				$"[{Path.Combine("group2", "key2")}]: read a vector3 from disk：{dataVector3.DiskData}"));
			return dataVector3.DiskData.ToString();
		}

 Object #

DataWrapper：DataTypeObject

写入数据：

		private string WriteObj()
		{
			DataObject dataObject = archiveManager.GetDataObject("group3", "key2");
			DataTypeObject dataTypeObject = dataObject.GetData<DataTypeObject>();
			dataTypeObject.Write(new Vector3Wrapper(new Vector3(6,6,6)));
			Debug.Log(string.Format($"[{Path.Combine("group3", "key2")}]: write a object ：{dataTypeObject.data}"));
			return dataTypeObject.data.ToString();
		}

读取数据：

		private string ReadObj()

			dictionary.Add(1.ToString(),new Vector3(1,1,1));
			dictionary.Add(2.ToString(),new Vector3(2,2,2));
			dictionary.Add(3.ToString(),new Vector3(3,4,4));
			dataDictionary.Write(dictionary);

 自定义类型 #

定义数据类型，详细见 创建自定义数据类型 - 温文的小屋 

		/// <summary>
		/// 1.create construct method
		/// </summary>
		public class CustomDataType : AbstractDataType<CustomData>
		{
			public CustomDataType(string dataStr) : base(dataStr){}
		}

		/// <summary>
		/// 2.override "ToString(CustomData)" function if would know detail data
		/// </summary>

		public class CustomData
		{
			public string author = "温文";
			public int code = 1;
			public double luckly = 1.0f;

			public override string ToString()
			{
				return "author: " + author +
					   " code: " + code +
					   " luckly: " + luckly;
			}
		}

获取持有CustomData值的数据对象

DataObject dataObject = archiveManager.GetDataObject("group3", "key2"); 
CustomDataType customDataType= dataObject.GetData<CustomDataType>();
