	因为资源的层太深的话，发通知会非常麻烦.(添加/删除/设置/读取...)
	所以，规定的Rule是对象层最多2层,发通知最多2层结构，再深入的内容都作为Context处理.

	一层结构：值对象, "KV":50.
		更新POINT： key= "KV",Context="50"

	二层结构：结构体对象,
	     "APR": {"KV":50,"MA":20,...}
		 更新POINT： key= "APR",Context="KV:50"

	二层结构：MAP对象
		"DevMap":{"Dev1":"Driver","Dev2":"Device",....}
		更新POINT： key= "DevMap",Context={"Dev1":"Driver"}

	嵌套三层结构：MAP<STRUCT>
		"AprMAP":{ "APR1":{"KV":50,"MA":20,...},"APR2":{"KV":50,"MA":20,...},...}
		更新POINT： (作为2层结构处理,就算只有一个KV节点变更,也要把整个对象发送过去.)

/*
	vector保存内容为[INT,FLOAT,STRING]的一种,
	如果是保存的内容为对象的情况,跟ResMap没有区别了,所以vector除了保存基础信息以外意义不大.

	重要：另一个问题是vector的存储内容不能重复,因为这样通知就非常暧昧,接收方不知道该更新哪个节点,后续有重复情况的时候需要再检讨.
	      所以,数组的节点必须是唯一的.

	可以GETCONTEXT/SETCONTEXT,ADD,DEL

	不要Update:Update操作调整为 DEL/ADD
	
	operator[](const char *pkey) 会失败且异常.


*/

/*
	以下原因暂时不支持VECTOR,后续的技术调整成功后会做出VECTOR.

	1.第一个最重要的原因是Boost库以XML文件形式读写JSON对象的时候,不支持JSON数组.

	2.现在版本用下标访问的地方太多，要一个一个排查.
	  如果对象中有数组的话,在资源内容传递过程中,中间一个环节用字符串下标访问数组会直接崩溃.

	3.ResDataObject现在还没有实现数组的套用,得做技术可行性分析,后续解决了套用数组的话,再考虑.

	4.现阶段只有驱动服务和总线驱动会受到影响,问题不大.
	  目前纯粹的基础数据表格,设备层还没有太大的必要.
