Cloning Graph::Directed Objects

arunhorne has asked for the wisdom of the Perl Monks concerning the following question:

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,

____________
Arun

Shouldn't `copy` do that ? From the docs: `$C = $G->copy; Returns a new graph $C corresponding to the graph $G.` [download] ---- amphiplex	[reply] [d/l]
