Class PolyDrawer

java.lang.Object

haberman.rhizomatics.map.PolyDrawer

class PolyDrawer
extends java.lang.Object

Since we can't set the stroke width of a polygon (issue #4087), this container stores the drawing of an area as both a Polyline and a Polygon. Also contains different public method for quick styling updates.
