提升子图和捆绑属性 [英] Boost Subgraph and Bundled properties
问题描述
我正在使用捆绑的属性和adjacency_list，并且想使用子图类.
I'm using bundled properties and adjacency_list and would like to use the subgraph class.
struct Vertex
{
int index;
int seed;
};
struct Edge
{
bool visted;
double weight;
};
typedef adjacency_list<listS, listS, undirectedS, Vertex, property<edge_index_t,int,Edge> > Graph;
typedef subgraph<Graph> testSubgraph;
需要property<edge_index_t,int,Edge>部分，因为子图需要edge_index_t来比较两个边.
The property<edge_index_t,int,Edge> part is needed, as subgraph needs edge_index_t to compare two edges.
现在我的问题是如何使用子图中的捆绑属性添加Edge?
在没有property<edge_index_t,int,Edge>的普通图中，我添加一条边，如下所示:
Now my question is how do I add an Edge using bundled properties in a Subgraph?
In the normal graph without property<edge_index_t,int,Edge> I add an edge as following:
Edge e;
vertex_descriptor u,v;
// fill in u and v;
e.weight = 1.0;
e.visted=false;
add_edge(u,v,e,graph);
但这不适用于Subgraph.
But this doesn't work for Subgraph.
希望有人知道解决方案.
Hope someone knows a solution for this.
谢谢

推荐答案
在尝试使用add_vertex()函数添加顶点时，我遇到了一个类似的问题，发现存在一个(很旧的)未解决的问题Boost Bugtracker:
I just ran into the a similar issue when trying to add a vertex with the add_vertex() function and found that there is a (very old) unresolved issue on the boost bugtracker:
图形适配器(例如子图形)不支持捆绑 属性，但它们应该.
The graph adaptors (such as subgraph) do not support bundled properties, but they should.
进一步的搜索导致以下两个补丁，这些补丁尚未合并，但似乎最终带来了对子图中捆绑属性的支持:
Further searching lead to the following 2 patches, which are not yet merged but appear to finally bring the support for bundled properties in subgraphs:
- Ticket #10708: Property support in add_vertex() method for subgraph
- Ticket #10709: Graph bundled property support in subgraph
所以我想答案是:现在，不要使用捆绑属性.但是将来，这个问题应该会消失.
So I guess the answer is: For now, don't use bundled properties. But in the future, the issue should disappear.
