Examples of java.util.Hashtable.clone()

java.util.Hashtable.clone()
Creates a shallow copy of this hashtable. All the structure of the hashtable itself is copied, but the keys and values are not cloned. This is a relatively expensive operation. @return a clone of the hashtable

        Hashtable env = cpe.getEnvironment();
        if (env == null) {
            env = new Hashtable(7);
        } else {
            // Make a (shallow) copy of the environment.
            env = (Hashtable) env.clone();
        }
        env.put(CPE, cpe);


        ContinuationContext cctx = new ContinuationContext(cpe, env);
        return cctx.getTargetContext();
