Re: [graph-tool] Accessing the integer attribute in Vertex/Edge object directly/faster

Hi,

Given a `graph_tool.Edge` instance, is it possible to directly access the integer value (or its index value) of the source vertex and target vertex?

My current solution is

``` s = int(e.source()) t = int(e.target()) ```

I have some function that calls the above routine many times and it is not fast enough. I am wondering if I can do it faster.

How could it be even more direct than the above?

Similarly, can I access the index/integer value of a Vertex object directly?

Just do: int(v) where is a Vertex instance. Best, Tiago -- Tiago de Paula Peixoto <tiago@skewed.de>
