Class GeoCircle


  • public class GeoCircle
extends Geometry
    The GeoCircle class.

    This class is mainly used in the CAD layer, it is the subobject of the Geometry object.

    • Constructor Detail

      • GeoCircle

        public GeoCircle()
        Constructs a new GeoCircle object.

      • GeoCircle

        public GeoCircle(GeoCircle geoCircle)
        Constructs a new object identical to the given GeoCircle object.
        Parameters:
        geoCircle - the specified GeoCircle object.

      • GeoCircle

        public GeoCircle(Point2D center,
                 double radius)
        Creates a new GeoCircle object according to the specified arguments.
        Parameters:
        center - Center
        radius - Radius

      • GeoCircle

        public GeoCircle(Point2D point1,
                 Point2D point2)
        Creates a new GeoCircle object according to the specified arguments.
        Parameters:
        point1 - One specified point which is one of the two end points of the diameter of the circle.
        point2 - Another specified point which is one of the two end points of the diameter of the circle.

      • GeoCircle

        public GeoCircle(Point2D point1,
                 Point2D point2,
                 Point2D point3)
