Cloning Graph::Directed Objects

[arunhorne]

Monks,

I have created a Graph::Directed object. I want to make a copy of it to work on whilst keeping the original graph intact (allowing me to easily revert to the original graph). I want to clone the object. However when I do the following:

$TMPGRAPH = $GRAPH

it is unsurprisingly the case that operating on TMPGRAPH alters GRAPH. How can I clone $GRAPH such that modifying TMPGRAPH will not affect $GRAPH?

Thanks,

Shouldn't copy do that ?

From the docs:

               $C = $G->copy;

       Returns a new graph $C corresponding to the graph $G.
