Method Detail

contains

public boolean contains(Point p)
Description copied from interface: Shape
Tells whether the shape encloses a given point. To the aims of this test, we consider the shape to be closed, so that a point lying on the shape's boundaries results as enclosed in the shape.

Specified by:
contains in interface Shape
Overrides:
contains in class Ray
Parameters:
p - the point we test for encloseness.
Returns:
true iff the point is enclosed in the shape.

draw

public void draw(java.awt.Graphics gfx)
Description copied from interface: Shape
Draws the shape, using the current graphics context's color.

Specified by:
draw in interface Shape
Overrides:
draw in class Ray
Parameters:
gfx - the graphics context where this shape has to be drawn.

drawLabels

public void drawLabels(java.awt.Graphics gfx)
Description copied from interface: Shape
Draws the shape's associated labels, using the graphics context's color.

Specified by:
drawLabels in interface Shape
Overrides:
drawLabels in class Ray
Parameters:
gfx - the graphics context where this shape's labels have to be drawn.

drawPoints

public void drawPoints(java.awt.Graphics gfx)
Description copied from interface: Shape
Draws the shape's defining points, using the graphics context's color.

Specified by:
drawPoints in interface Shape
Overrides:
drawPoints in class Ray
Parameters:
gfx - the graphics context where this shape's points have to be drawn.

getPoints

public java.util.List getPoints()
Shape Implementation

Specified by:
getPoints in interface Shape
Overrides:
getPoints in class Ray
Returns:
the shape's cloned defining points.

intersect

public int intersect(Segment s)
