| Constructor Summary | |
| protected | Circle()
Creates a circle with center [0,0] and radius = 0. | | protected | Circle(DirectPosition center, double radius)
Creates a circle using the specified center and radius. |
| Method Summary | |
| protected boolean | contains(DirectPosition p)
The contains test whether the coordinate p is within the circle.
Triangle contains coordinate if the distance between center and p is
smaller then the radius that is reduced by tolerance. | | protected DirectPosition | getCenter()
Returns the coordinate of the center. | | protected double | getRadius()
Returns the radius. | | protected double | getTolerance()
| | protected void | setCenter(DirectPosition center)
Sets the center. | | protected void | setRadius(double radius)
Sets the radius. | | protected void | setTolerance(double tolerance)
Sets the tolerance for the contains method. |
| Circle | | protected Circle()(Code) | | Creates a circle with center [0,0] and radius = 0.
|
| Circle | | protected Circle(DirectPosition center, double radius)(Code) | | Creates a circle using the specified center and radius.
Parameters:
center - of the circle.
Parameters:
radius - of the circle. |
| contains | | protected boolean contains(DirectPosition p)(Code) | | The contains test whether the coordinate p is within the circle.
Triangle contains coordinate if the distance between center and p is
smaller then the radius that is reduced by tolerance. This is used for
triangulation when there are four points on one circle to avoid
neverending loop.
Parameters:
p - - the point to be tested True if the circle contais p, False if not. |
| getCenter | | protected DirectPosition getCenter()(Code) | | Returns the coordinate of the center.
center coordinates |
| getRadius | | protected double getRadius()(Code) | | Returns the radius.
radius value. |
| getTolerance | | protected double getTolerance()(Code) | | Raturns the tolerance
tolerance value |
| setCenter | | protected void setCenter(DirectPosition center)(Code) | | Sets the center.
Parameters:
center - coordinates |
| setRadius | | protected void setRadius(double radius)(Code) | | Sets the radius.
Parameters:
radius - value |
| setTolerance | | protected void setTolerance(double tolerance)(Code) | | Sets the tolerance for the contains method.
Parameters:
tolerance - value |
