Class AbstractRenderer

java.lang.Object
org.jfree.chart.renderer.AbstractRenderer
All Implemented Interfaces:
Serializable, Cloneable
Direct Known Subclasses:
AbstractCategoryItemRenderer, AbstractXYItemRenderer, DefaultPolarItemRenderer, WaferMapRenderer
public abstract class AbstractRenderer extends Object implements Cloneable, Serializable
Base class providing common services for renderers. Most methods that update attributes of the renderer will fire a RendererChangeEvent, which normally means the plot that owns the renderer will receive notification that the renderer has been changed (the plot will, in turn, notify the chart).
