public interface PieURLGenerator
Interface for a URL generator for plots that use data from a
PieDataset
.
Classes that implement this interface should be either (a) immutable, or
(b) cloneable via the PublicCloneable
interface (defined in
the JCommon class library). This provides a mechanism for the referring
plot to clone the generator if necessary.
