Interface Circle

All Superinterfaces:

Comparable, Geometry, OrientablePrimitive, OrientableSurface, Primitive, Serializable, Shape, Surface

All Known Implementing Classes:

Circle2D, Circle2DZ

public interface Circle
extends Surface

This interface is equivalent to the GM_Circle specified in ISO 19107. Same as Arc, but closed to form a full circle. The "start" and "end" points are equal.

Method Detail

setPoints

void setPoints(Point center,
               Point radious)

Sets the two values to define a circle.

Parameters:

center - The center point of the circle.

radious - A point that is used to calculate the radius.

setPoints

void setPoints(Point center,
               double radious)

Sets the two values to define a circle.

Parameters:

center - The center point of the circle.

radious - The radius of the circle.

setPoints

void setPoints(Point p1,
               Point p2,
               Point p3)

Sets the values to define a circle from three points. The circle will be inside or the area defined by the three points.

Parameters:

p1 - First point

p2 - Second point

p3 - Third point

getCenter

Point getCenter()

Returns the center of the circle.

Returns:

The center of the circle.

getRadious

double getRadious()

Returns the radius of the circle

Returns:

The radius of the circle
