public abstract class AbstractClassifiedVectorLegend extends AbstractVectorialLegend implements org.gvsig.fmap.mapcontext.rendering.legend.IClassifiedVectorLegend
Abstract class that implements the interface for legends composed by classified symbols.It will have two methods that will be executed depending on the action that had been done with the legend (addition of a new symbol or clear the legend).
