使用boost ::结合性地图的boost :: BIMAP接口 [英] Using boost::associative property map with boost::BIMAP interface

问题描述

我不能够实现升压关联属性映射接口，用于提振bimap的。

I am not able to implement associative property map interface of boost for a boost bimap.

我有一个bimap的如下，我尝试定义一个boost ::关联属性映射它。我想使用PUT和GET辅助功能为我的bimap的..在code是如下：

I have a bimap as follows and I try to define a boost::associative property map for it. I want to use Put and Get helper functions for my bimap.. the code is as follows:

 typedef boost::bimaps::bimap< vertex_descriptor_t, size_t >       vd_idx_bimap_t;
 typedef boost::associative_property_map< vd_idx_bimap_t >         asso_vd_idx_bimap_t;

 // define bimap
 vd_idx_bimap_t        my_bimap;
 asso_vd_idx_bimap_t   my_asso_bimap(my_bimap);

我得到一个编译错误为

I get a compile error as

  error: no type named âsecond_typeâ in âboost::bimaps::container_adaptor::container_adaptor<boost::multi_index::detail::ordered_index<boost::m.... goes on long list. 

据我所知，bimaps是通过属性映射支持。看<一个href=\"http://www.boost.org/doc/libs/1_55_0/libs/bimap/doc/html/boost_bimap/bimap_and_boost/boost_libraries_that_work_well_with_boost_bimap.html#boost_bimap.bimap_and_boost.boost_libraries_that_work_well_with_boost_bimap.boost_property_map\"相对=nofollow>这里文档。只是不知道如何将我使用关联属性映射它..如果我能为我的关联属性映射定义向左或向右bimap的，这也将被罚款。请建议。

I am aware, bimaps are supported through property maps. see here for documentation. Just wondering how would i use associative property map for it.. if i can define left or right bimap for my associative property map, that would also be fine. please suggest.

推荐答案

您需要告诉它的哪边的bimap的使用方法：

You need to tell it which side of the bimap to use:

typedef boost::associative_property_map<vd_idx_bimap_t::left_map> asso_vd_idx_bimap_t;
// OR
typedef boost::associative_property_map<vd_idx_bimap_t::right_map> asso_vd_idx_bimap_t;

所以，看到它的 住在Coliru

So, see it Live on Coliru

#include <boost/bimap.hpp> 
#include <boost/property_map/property_map.hpp> 
#include <iostream> 

using namespace boost; 

int main() 
{
    typedef int vertex_descriptor_t;
    typedef boost::bimaps::bimap< vertex_descriptor_t, size_t > vd_idx_bimap_t;
    typedef boost::associative_property_map<vd_idx_bimap_t::left_map>   asso_vd_idx_bimap_t;

    // define bimap
    vd_idx_bimap_t        my_bimap;
    asso_vd_idx_bimap_t   my_asso_bimap(my_bimap.left);
}
