Methods

o getChildAt 
 public MapElement getChildAt(RelPoint pl)
Find child element at the specified position.

Parameters:
pl - The position within this element's area.
Returns:
a reference to the child element if found, a reference to this element otherwise.
o rand 
 protected int rand()
Create pseudorandom numbers. The value is bounded by maxrand.

o scalePoint 
 protected RelPoint scalePoint(RelPoint pt,
                               Stack layout)
Do a complete scaling on a point.

Parameters:
pt - the point to scale.
layout - stack of all layouts in effect.
Returns:
scaled point.
o drawChildren 
 protected void drawChildren(Graphics g,
                             MapDrawer contr,
                             Stack layout,
                             int level)
Draw this element's children.

o areaToPolygon 
 protected Polygon areaToPolygon(Rectangle bounds,
                                 Stack layout,
                                 Vector v)
Scale every point in a given polygon.

Parameters:
bounds - the Rectangle into which the polygon should be scaled.
layout - stack of all layouts in effect.
v - the original polygon, as a vector of RelPoints
Returns:
the scaled polygon.
o draw 
 public void draw(Graphics g,
                  MapDrawer contr,
                  Stack layout,
                  int level)
Draw this element.

Parameters:
g - Graphics context
contr - the MapDrawer who wants to draw this element
layout - a stack of applying layouts.
level - tells whether we should draw deeper elements
o setParent 
 public void setParent(ParseElement p)
o getParent 
 public ParseElement getParent()
o addChild 
 public void addChild(ParseElement p)
o setProperty 
 public int setProperty(MapDProp p)
Supported properties: name, place, color

o getProperty 
 public int getProperty(MapDProp p)
