Interface PieURLGenerator

All Known Implementing Classes:

CustomPieURLGenerator, StandardPieURLGenerator

public interface PieURLGenerator

Interface for a URL generator for plots that use data from a PieDataset. Classes that implement this interface:

• 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;
• 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

java.lang.String

generateURL(PieDataset dataset, java.lang.Comparable key, int pieIndex) Generates a URL for one item in a PieDataset.

Method Detail

generateURL

java.lang.String generateURL(PieDataset dataset,
                             java.lang.Comparable key,
                             int pieIndex)

Generates a URL for one item in a PieDataset. As a guideline, the URL should be valid within the context of an XHTML 1.0 document.

Parameters:

dataset - the dataset (null not permitted).

key - the item key (null not permitted).

pieIndex - the pie index (differentiates between pies in a 'multi' pie chart).

Returns:

A string containing the URL.
