[Ns-developers] uint16_t const parameter?

[Gustavo Carneiro]

Hi,

I am working on python bindings, and I see this:

static void ns3::PointToPointTopology::SetIpv4Metric(ns3::Ptr<const
ns3::PointToPointChannel> chan, ns3::Ptr<ns3::Node> n1, ns3::Ptr<ns3::Node>
n2, uint16_t const metric)

I am wondering what is the point of "uint16_t const metric" and why it can't
be just "uint16_t metric".  Any thoughts?  I mean, I could easily support it
in the python bindings, but it seems kind of silly anyway, unless I miss
something...

Thanks,
