Subject instance variable reference to class variable
Date Fri, 08 Mar 2002 14:25:21 GMT
Hello tomcat developers,

In tomcat 4.0.4-b1 src code I had a quick look thru and found the following
in org.apache.catalina.cluster:

public class MulticastSender
    extends ClusterSessionBase implements ClusterSender {

    // ----------------------------------------------------- Instance
Variables

    /**
     * The unique message ID
     */
    private static String senderId = null;

    /**
     * The name of our component, used for logging.
     */
    private String senderName = "MulticastSender";

    /**
     * The MulticastSocket to use
     */
    private MulticastSocket multicastSocket = null;

    /**
     * The multicastAdress this socket is bound to
     */
    private InetAddress multicastAddress = null;

    /**
     * The multicastPort this socket is bound to
     */
    private int multicastPort;


    // --------------------------------------------------------- Public
Methods


    /**
     * Create a new MulticastSender, only receivers with our
     * senderId will receive our data.
     *
     * @param senderId The senderId
     * @param multicastSocket the socket to use
     * @param multicastAddress the address to use
     * @param multicastPort the port to use
     */
    MulticastSender(String senderId, MulticastSocket multicastSocket,
                    InetAddress multicastAddress, int multicastPort) {
        this.multicastAddress = multicastAddress;
        this.multicastPort = multicastPort;
        this.multicastSocket = multicastSocket;
        this.senderId = senderId;


The senderId is static ( a class variable, yes? ) but the comment says that
it is an instance variable and in the constructor it is refered to as an
instance variable instead of a class variable. Is this intentional?

regards,

Chris Munroe.
