public interface Shape

contains

boolean contains(Point p)

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.

Parameters:

p - the point we test for encloseness.

Returns:

true iff the point is enclosed in the shape.

draw

void draw(java.awt.Graphics gfx)

Draws the shape, using the current graphics context's color.

Parameters:

gfx - the graphics context where this shape has to be drawn.

drawLabels

void drawLabels(java.awt.Graphics gfx)

Draws the shape's associated labels, using the graphics context's color.

Parameters:

gfx - the graphics context where this shape's labels have to be drawn.

drawPoints

void drawPoints(java.awt.Graphics gfx)

Draws the shape's defining points, using the graphics context's color.

Parameters:

gfx - the graphics context where this shape's points have to be drawn.

getLabel

java.lang.String getLabel()

Returns the text label associated to this shape.

Returns:

the shape's label.

getPoints

java.util.List getPoints()

Returns a list containing copies of the shape's defining points.

Returns:

the shape's cloned defining points.

setLabel

void setLabel(java.lang.String label)

Associates this shape with a given text label.

Parameters:

label - the shape's new label.

translate

void translate(int dx,
               int dy)

Translates the shape by the given amount.

Parameters:

dx - the amount to translate along the X-axis

dx - the amount to translate along the Y-axis
