[Neutron API] What is the efficient way to get the port by its fixed IP?

[Raj <ra...@apache.org>]

Hi,

If I know the fixed IP, what is efficient way of getting the port which is
associated with this IP, using neutron api?

Currently I am doing like below, but it is not efficient.

   - List all the ports using port API
   - go through each port and get all fixed IPs
   - go through each fixed IP and check whether it is equal to my fixed IP.

          List<Port> ports = api.list().concat().toList();
          for (Iterator<Port> iterator = ports.iterator();
iterator.hasNext();) {
                Port port = (Port) iterator.next();
                for (IP ip : port.getFixedIps()) {
                    if (ip.getIpAddress().equals(myFixedIP)) {
                        // so this "port" is what I am searching
                    }
                }
          }

Is there any efficient way to do this?

Thanks.

Or we can do the same with predicates;

    private Iterable<Port> getPortByFixedIP(final String fixedIP) {
        Iterable<Port> port =
Iterables.filter(portApi.list().concat().toList(),
                new Predicate<Port>() {
            @Override
            public boolean apply(Port input) {
                for (IP ip : input.getFixedIps()) {
                    if (ip.getIpAddress()!= null
                            && ip.getIpAddress().equals(fixedIP)){
                        return true;
                    }
                }
                return false;
            }
        });
        return port;
    }

This will return the list of ports which is associated with the given fixed
IP right?

Am I correct?

Thanks.
