Interface PieURLGenerator

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.

Method Summary
