问题描述
在C ++ 03中没有< vectorfwd>
样文件,而有< iosfwd>
header。 $ b $ p
更新:
我收到了语言创建者的回答:实际上不可能要求所有STL供应商提供此信息 >
解决方案
不,没有新的转发文件,只是旧的< iosfwd>
。
完整的I / O系统与向量相比很大,所以优势可能不会太大。
In C++03 there are no <vectorfwd>
-like files, while there is the <iosfwd>
header. Will this change in the future?
It could be valuable to reduce dependencies and for better modularity.
UPDATE:
I have received an answer from the language creator: "practically it's not possible to require this from all STL vendors".
解决方案
No, there are no new forward files, just the old <iosfwd>
.
The complete I/O-system is large compared to a vector, so the advantage would perhaps not be that significant.
