网站空间会过期吗,网站 网页制作,网站简历,wordpress小工具浮动这段时间突发奇想#xff0c;觉得可以弄一个Json和C各种数据类型互转的工具#xff0c;因为Json在进行数据储存的时候#xff0c;有一些先天的优势#xff0c;传统的C的序列化方式是将数据序列化到流数据里面#xff0c;而流数据是典型的串行结构#xff08;或则说是一维… 这段时间突发奇想觉得可以弄一个Json和C各种数据类型互转的工具因为Json在进行数据储存的时候有一些先天的优势传统的C的序列化方式是将数据序列化到流数据里面而流数据是典型的串行结构或则说是一维结构因此流数据对数据的位置特别的敏感一旦序列化的元素有调整就会导致原来存储的流数据完全失效。这一点在游戏开发时非常的麻烦我们不得不将各个接口进行拆分让接口对应其独自的流数据做到局部的隔离。但是这个办法也不是万能因为一旦接口内某些元素顺序因为开始时过于简单而并没有做拆分时隐藏的风险种子就种下了。随着时间推移一旦需要更改这些元素时就会发现被锁死了手脚 Json具有结构化的特征涵盖了原型数组对象等数据类型用来做存储是非常理想的如果项目中存储的数据用Json存储然后再序列化到二进制流数据内这样似乎就结合了两者的优点结合了速度和可扩展性。而我自己写的CJson类本身就是可以序列化到流数据的。而且从流数据恢复的速度远比解析Json字符串的速度快几倍那么现在欠缺的就是如何将C数据转换成CJson类。 思考了一段时间我意识到 Jsonlizer 和 Serializer 有本质的区别一个是构建层次结构一个是构建一维结构我本来想尽可能的复用Serializer的代码但我意识到这是不可能的。我能利用的可能仅仅是一部分最基本的被称为 trait 模板代码。 而想复用Serialize函数的想法是不可能的。毕竟一个是结构化的数据一个是一维数据。于是我改变了策略重新构造了Jsonlizer。首先要做的是重写整个Jsonlizer的模板代码。这部分代码非常的关键就是用于识别C的各类数据。 这几个文件的代码如下

}
准备了两个类这两个类有聚合关系。然后我初始化这两个类然后用Jsonizer将这个类导出成Json数据结构。 tagTest2 in, out;in.index 1;in.value[0].index 101;in.value[0].name 101;in.value[1].index 102;in.value[1].name 102;in.value[2].index 103;in.value[2].name 103;in.value[3].index 104;in.value[3].name 104;CJsonlizer jr;jr in;CJson json;jr.Obtain( json );a_string value json.Stringify();printf( %s\n, value.c_str() );
运行的结果如下 其实并不困难。大家也可以试试其中 trait 的那些代码可以去看看boost的序列化相关的代码。
