[Lemon-user] How to know if a graph have already a node

[Pierre Moulon]

Hi,

I want to know if we could know if a graph have already a node register to
the element we want to potentially re-add :

I have test the find (stl) function over the graph note iterator, but it do
not compiles :

using namespace lemon; //ask if the graph g already contain a node nodeA.
graphType::NodeIt itA = find<graphType::NodeIt,Node>( graphType::NodeIt(g),
INVALID, nodeA);

Do you have a tip to give me ?


Regards,
Pierre
