Constructor Detail

### BoundingCircle.Impl

    public BoundingCircle.Impl(Geo center,
                               double radius)

### BoundingCircle.Impl

    public BoundingCircle.Impl(GeoArray arrayPoints)

### BoundingCircle.Impl

    public BoundingCircle.Impl(GeoPath path)

### BoundingCircle.Impl

    public BoundingCircle.Impl(Geo[] gs)

Method Detail

### init

    protected void init(Geo[] region)

  Works by computing the centroid, then finding the largest radius. This will not, in general, produce the minimal bounding circle.

### init

    protected void init(GeoArray region)

  Works by computing the centroid, then finding the largest radius. This will not, in general, produce the minimal bounding circle.

### init

    protected void init(Geo center,
                        double radius)

### getCenter

    public final Geo getCenter()

  Description copied from interface: `BoundingCircle`
  Returns a Geo representing the center of the circle.

  Specified by:
    `getCenter` in interface `BoundingCircle`
  Returns:
    Geo

### getRadius

    public final double getRadius()

  Specified by:
    `getRadius` in interface `BoundingCircle`
  Returns:
    the radius of the bounding circle in radians.

### intersects

    public boolean intersects(BoundingCircle bc)

  Specified by:
    `intersects` in interface `BoundingCircle`
  Returns:
    whether this bounding circle intersects with another.

### intersects

    public boolean intersects(Geo g,
                              double r)

  Specified by:
    `intersects` in interface `BoundingCircle`
  Returns:
    whether this bounding circle intersects with a Geo with a radius (radians) around it.

### toString

    public java.lang.String toString()
