old thread, but I think it's relevant to my issue. My interest is mostly in
the python interface to pcbnew.[0]


With the new connectivity stuff, what's the proper way to ask a net what
pads belong to it?

In python, I used to be able to do net.Pads() [1]

I tried adding connectivity.h[2] to boards.i via a new connectivity.i but
then I realized that GetConnectedPads can't take a net. net is not a
board_connected_item

I could iterate through all pads and compare each one's net. Seems like a
not so good way to do it.

I do see that the implementation of GetPadCount(aNet) does just that.[3]
Also, in that implementation, it's referencing connAlgo's padList. Is this
better than asking board for its pads? I'm thinking the whole "don't repeat
yourself" thing [4]

So, what is the recommended way to get a net's list of pads?

Miles

[2]: shouldn't this be called class_connectivity_data.h?


[3] here's GetPadCount
unsigned int CONNECTIVITY_DATA::GetPadCount( int aNet ) const
{
    int n = 0;

    for( auto pad : m_connAlgo->PadList() )
    {
        if( !pad->Valid() )
            continue;

        auto dpad = static_cast<D_PAD*>( pad->Parent() );

        if( aNet < 0 || aNet == dpad->GetNetCode() )
        {
            n++;
        }
    }

    return n;
}
