Hi all,
I want to derive a class from adjacency_list :
template <class NodesContainer = boost::vecS,
class EdgesContainer = boost::vecS,
class Directed = boost::undirectedS,
class NodesAttributes = boost::no_property,
class EdgesAttributes = boost::no_property
> class BGL_Graph : public boost::adjacency_list<NodesContainer,
EdgesContainer,
Directed,
NodesAttributes,
EdgesAttributes
>
{
/// ... many typedefs
/// ...
};
I also have an other derived class from BGL_Graph :
class MPPRectangleGraph : public
BGL_Graph<boost::vecS,boost::vecS,boost::undirectedS,MPPRectangleGraphNode,Weight>
{
public:
MPPRectangleGraph() {is_init_ = false;};
~MPPRectangleGraph();
void InitDisplay(std::string name = "MPP",
unsigned int width = 200,
unsigned int height = 200);
void Draw( unsigned int flags = DRAW_NOTHING);
void Display( unsigned int flags = DRAW_NOTHING );
protected:
private:
bool is_init_;
IdFenetreCalques window_;
IdCalqueVecteur layer_rectangle_;
IdCalqueVecteur layer_profiles_;
IdCalqueVecteur layer_neighborhood_;
IdCalqueVecteur layer_edges_;
};
My problem is how can I iterate on the edges in a method of
MPPRectangleGraph ?
void MPPRectangleGraph::Draw( unsigned int flags )
{
// On recupere les differents flags d'affichage
bool draw_rect = false, draw_profiles = false, draw_neighborhood =
false, draw_edges = false;
if ( flags&DRAW_RECTANGLE )
draw_rect = true;
if ( flags&DRAW_PROFILES )
draw_profiles = true;
if ( flags&DRAW_NEIGHBORHOOD )
draw_neighborhood = true;
if ( flags&DRAW_EDGES )
draw_edges = true;
// On vide tous les calques
layer_rectangle_.Clear();
layer_profiles_.Clear();
layer_neighborhood_.Clear();
layer_edges_.Clear();
// On fait l'affichage en fonction des flags recuperes
// Les aretes
MPPRectangleGraph::edge_iterator first, last;
for(boost::tie(first, last)=edges(this);first!=last;++first) // does not
work !
{
//std::cout << boost::source(*first, g) << " to " <<
boost::target(*first, g) << " = ";
}
}
Regards
