Hello all.
I'm having issues getting property maps to work properly with my
custom adjacency_list. Here's a snippet of the code:
// Definitions
// define some of the properties the graphs will have
// http://www.boost.org/doc/libs/1_42_0/libs/graph/doc/using_adjacency_list.htm...
struct posx_t { typedef vertex_property_tag kind; };
struct posy_t { typedef vertex_property_tag kind; };
typedef property VertexPosX;
// chain to add in posy
typedef property VertexPos;
// chain to add in vertex_index
typedef property VertexProperty;
// define our special graph
typedef adjacency_list > AGraph;
...
template<class T>
void boostToVAGraph(const AGraph & g,
const int num_nodes, const int num_edges,
T ** idata,
T ** odata,
unsigned int ** segment_descriptor,
unsigned int ** cross_pointers,
unsigned int ** head_flags,
T ** reference,
const testrigOptions & testOptions)
{
typedef AGraph Graph;
// define the manipulator for our special properties
// http://www.boost.org/doc/libs/1_42_0/libs/graph/doc/using_adjacency_list.htm...
// requires property_map.hpp
// BROKEN!!!!!
property_map::type
getposx = get(posx_t(), g);
property_map::type
getposy = get(posy_t(), g);
...
I used another function to generate the AGraph and apply values. And
using property map there seems to work. However, I then pass it to
this function using:
boostToVAGraph(g, num_nodes, num_edges, idata, odata, segment_descriptor,
cross_pointers, head_flags, reference,
testOptions);
On compile, I get this error:
1>agraph.cpp

Ideas?
