We weren't/aren't - the last piece is how to handle persisting the
information
in the above code snippet, which could then be appended to the cloned
local_ids
for the final result. What I thought of during the day (and I was still
looking
for something more efficient) would be to use a hashmap that included the
binding_rec uuid and the logical_port string - then I could just check to
see if
the string already existed on the add side, and remove the value based on
the
uuid on the delete side.
