Something like:

-- called when "greaterthan" message is received at first inlet -- atoms is a table of the atoms in the message following the selector function M:in_1_greaterthan(atoms) local name = atoms[1] -- could be: "score" local value = atoms[2] -- could be: 3 if name ~= nil and value ~= nil then -- could check types too.. -- do your stuff here end end

If you have a range of possible selectors, and don't want to have to write a method for all of them, you can use:

function M:in_1(selector, atoms) ... end

Then selector will be "greaterthan" (or whatever) and atoms will be as above.
