C ++中的多维容器 [英] Multidimensional Containers in C++

问题描述

有没有任何库提供多维容器来使用像向量<>？

我想看到像：

  TwoD< object_class_name> D2; 
 ThreeD< object_class_name> D3; 
  

且object_class_name可以是任何对象而不是内置类型。

，所以我可以使用

  D2 [i] [j] 
 D3或者类似的 
 $ 

D3 [i，j，k] p>



感谢。

解决方案

如果是c ++ 11， 使用 ，允许将 template ：

  template< typename T& 
 using TwoD = std :: vector< std :: vector< T>> 
 
 template< typename T> 
 using ThreeD = std :: vector< std :: vector< std :: vector< T>>> 
  

用法：

 code> TwoD< int> t2ints; 
 TwoD< std :: string> t2strings; 
 
 ThreeD< int> t3ints; 
 ThreeD< std :: string> t3strings; 
  

Is there any library provide a multidimensional container to use like vector<>?

I would like to see something like:

TwoD<object_class_name> D2;
ThreeD<object_class_name> D3;

and the object_class_name could be any object instead of only the builtin types.

so I can use the object like

D2[i][j]
D3[i,j,k] or D3(i,j,k)

or similar

Thanks.

解决方案

If c++11, a possible solution is using which allows aliasing of a template:

template <typename T>
using TwoD = std::vector<std::vector<T>>;

template <typename T>
using ThreeD = std::vector<std::vector<std::vector<T>>>;

usage:

TwoD<int> t2ints;
TwoD<std::string> t2strings;

ThreeD<int> t3ints;
ThreeD<std::string> t3strings;
