Constructor Detail

Oval

public Oval(double x,
            double y,
            double width,
            double height,
            DrawingCanvas canvas)

Constructs a new oval bounded by a rectangle with upper left corner at (x,y) and dimensions given by width and height.

Parameters:

x - coordinate of the upper left corner of the bounding rectangle

y - coordinate of the upper left corner of the bounding rectangle

width - the width of the bounding rectangle

height - the height of the bounding rectangle

canvas - the canvas in which the oval is created

Oval

public Oval(Location origin,
            double width,
            double height,
            DrawingCanvas canvas)

Parameters:

origin - the upper left corner of the bounding rectangle

width - the width of the bounding rectangle

height - the height of the bounding rectangle

canvas - the canvas in which the oval is created

Oval

public Oval(Location p0,
            Location p1,
            DrawingCanvas canvas)

Constructs a new oval bounded by a rectangle with diagonal given by a line from p0 to p1.

Parameters:

p0 - endpoint of a diagonal of the bounding rectangle

p1 - other diagonal endpoint

canvas - the canvas in which the object is created

Method Detail

contains

public boolean contains(Location point)

Description copied from interface: DrawableInterface

Determines if a particular position on the DrawingCanvas is contained within the object.

Specified by:

contains in interface DrawableInterface

Overrides:

contains in class Drawable2D

Parameters:

point - the position on the canvas.

Returns:

true if point is contained in the object, false otherwise.
