SessionMap
public class SessionMap extends AbstractMap implements Serializable(Code)
A simple implementation of the java.util.Map interface to handle a collection of HTTP session attributes. The SessionMap.entrySet() method enumerates over all session attributes and creates a Set of entries. Note, this will occur lazily - only when the entry set is asked for.
