Interface IPolygon

public interface IPolygon

A generic polygon used as the base class for more complex shapes. Each polygon has a set of vertices and a "central" point, often used for a label. The "central" point does not need to be in the centre.

Field Summary

static IPolygon[]

ZERO

Method Summary

IXyz	centralPoint() Returns the location of the central point
void	centralPoint(IXyz t) Set the location of the central point
boolean	contains(IXyz p) Returns true if given point is inside the boundary of the polygon
IObstacle	overlapping(IObstacle obstacle)
boolean	overlapping(IPolygon that) Returns true if this polygon overlaps the given one
void	translate(IXyz ab) Translate all the vertices of this polygon
IXyz[]	vertices() The vertices defining the boundary of the polygon
