运行时结构的定义 [英] Runtime Definition of a struct
问题描述
我不认为这是可能的，但是，如果有人对某项作品发表评论
那将是很好的。让我解释一下我想这样做的原因。
这样做。假设您获得了一个文件，其中包含一个标题，该标题定义了文件中包含的一组数据的结构。如果你在阅读文件标题之前不知道
结构是什么
你将如何在代码中使用它？
任何评论都将不胜感激。
I don''t think this is possible but, if anyone has comments on a work
around that would be great. Let me explain the reason I would like to
do this. Suppose you are given a file that contains a header defining
a structure for a set of data that is contained in the file. If you do
not know what the structure is before you read the header of the file
how would you work with this in code?
Any comments would be greatly appreciated.

假设你知道如何处理文件中的数据类型，你可以将它b / b
读入std :: map< Type，std :: string>并根据他们的类型处理基于
的值。

Assuming you know how to process the datatypes in the file, you could
read it into a std::map<Type,std::string> and process the values based
on their type.
