Class StrokeMap

java.lang.Object
org.jfree.chart.StrokeMap
All Implemented Interfaces:
Serializable, Cloneable
public class StrokeMap extends Object implements Cloneable, Serializable
A storage structure that maps Comparable instances with Stroke instances.

To support cloning and serialization, you should only use keys that are cloneable and serializable. Special handling for the Stroke instances is included in this class.
