Class Polygon

  • All Implemented Interfaces:
    java.io.Externalizable, java.io.Serializable, java.lang.Cloneable, java.lang.Comparable<Shape>
    public final class Polygon
extends AbstractPolygon
    Defines a polygon.

    Given a list of points, the polygon is the area inside the figure created by joining each pair of adjacent points by a line segment. The first and last points are also joined; you do not need to repeat the first point in order to close the polygon.

    A polygon whose edges cross each other may have unpredictable behavior. A point exactly on the edge of a polygon may fall inside or outside the polygon unpredictably. A point very close to an edge may seem to fall in the wrong area because of implications of floating-point arithmetic.

    WARNING: this API is experimental and will likely change in the near future.
