Class AbstractRenderer

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable
    Direct Known Subclasses:
    AbstractCategoryItemRenderer, AbstractXYItemRenderer, DefaultPolarItemRenderer, WaferMapRenderer

    public abstract class AbstractRenderer
    extends java.lang.Object
    implements java.lang.Cloneable, java.io.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).

        public void notifyListeners​(RendererChangeEvent event)
        Notifies all registered listeners that the renderer has been modified.
        Parameters:
        event - information about the change event.
