 * Interface for a URL generator for plots that use data from a
 * {@link PieDataset}.  Classes that implement this interface:
 * <ul>
 * <li>are responsible for correctly escaping any text that is derived from the
 *     dataset, as this may be user-specified and could pose a security
 *     risk;</li>
 * <li>should be either (a) immutable, or (b) cloneable via the
 *     <code>PublicCloneable interface (defined in the JCommon class
 *     library).  This provides a mechanism for the referring plot to clone
 *     the generator if necessary.</li>
 * </ul>
public interface PieURLGenerator {

     * Generates a URL for one item in a {@link PieDataset}. As a guideline,
     * the URL should be valid within the context of an XHTML 1.0 document.
     * @param dataset  the dataset (<code>null not permitted).
     * @param key  the item key (<code>null not permitted).
     * @param pieIndex  the pie index (differentiates between pies in a
     *                  'multi' pie chart).
     * @return A string containing the URL.
