Class MarkerFactory

java.lang.Object
  de.fhpotsdam.unfolding.data.MarkerFactory

public class MarkerFactory
extends java.lang.Object

A factory to create markers from features. The factory creates appropriate markers the each feature type, e.g. a polygon marker for a polygon feature, and handle multi-marker from multi-feature, as well.

See the following example on how to use this factory to create your own custom markers. For this, set the marker class for each feature type with the setPointClass(Class) etc methods.

 MarkerFactory markerFactory = new MarkerFactory();
 markerFactory.setPolygonClass(MyPolygonMarker.class);
 List<Marker> markers = markerFactory.createMarkers(features);
 

By default, this factory creates the simple markers provided by Unfolding, such as SimplePointMarker.
