public class GraphOval
extends GraphUnit
Oval/Ellipse in its native form Mapping (xmin, ymin) --> (top left) of the rectangle that encloses the oval (xmax, ymax) --> (width, height) of the enclosing rectangle

Constructor Index

o GraphOval(int, int, Color)
Creates an Instance of Partial Oval with its starting point the top left set along with the Color and type
o GraphOval(int, int, int, int, Color)
Creates a Oval that is complete in all aspects of its definition although the enclosing rectangle arguments are start and end points of the user interaction, it appropriately identifies the left top and width and height
o GraphOval(DataInputStream)
Creates an instance of the GraphOval by reading the data from the Input Stream.

Method Index

o addnext(int, int)
Add next assumes that the input is referred to as the final point of user's description of the enclosing rectangle's diagonal.
o erase(Graphics, Color)
renders the Oval to the graphics using the background color (this) in XOR mode.
o isInside(int, int)
method to verify if the passed point is enclosed in the handles of this Object.
o paint(Graphics)
renders the Oval to the graphics using the current color (this)

Constructors

o GraphOval 
  public GraphOval(int x1,
                   int y1,
                   Color arg)
Creates an Instance of Partial Oval with its starting point the top left set along with the Color and type
Parameters:
x1 - the x coordinate of the starting point
y1 - the y coordinate of the starting point
arg - the color of this rectangle.

o GraphOval 
  public GraphOval(int x1,
                   int y1,
                   int x2,
                   int y2,
                   Color arg)
Creates a Oval that is complete in all aspects of its definition although the enclosing rectangle arguments are start and end points of the user interaction, it appropriately identifies the left top and width and height
Parameters:
x1 - the x coordinate of the starting point
y1 - the y coordinate of the starting point
x2 - the x coordinate of the end point
y2 - the y coordinate of the end point
arg - the color of this oval.
o GraphOval 
  public GraphOval(DataInputStream din) throws IOException
Creates an instance of the GraphOval by reading the data from the Input Stream. It then fills up the member variables of the class
Parameters:
din - DataInputStream the stream from which the data is read
Throws: IOException
if an I/O error occurs

ByteUnPackInputStream, packetize

Methods

o addnext 
  public void addnext(int x,
                      int y)
Add next assumes that the input is referred to as the final point of user's description of the enclosing rectangle's diagonal. Hence, it corrects the data in xmin, ymin such that they map to top left and xmax, ymax to width and height respectively.
Parameters:
x - int x-coordinate
y - int y-coordinate
Overrides:
addnext in class GraphUnit
o paint 
  public void paint(Graphics g)
renders the Oval to the graphics using the current color (this)
Parameters:
g - Graphics to which it is rendered.
Overrides:
paint in class GraphUnit
o erase 
  public void erase(Graphics g,
                    Color arg)
renders the Oval to the graphics using the background color (this) in XOR mode.
Parameters:
g - Graphics to which it is rendered.
arg - COlor of the background
Overrides:
erase in class GraphUnit
o isInside 
  public boolean isInside(int x,
                          int y)
method to verify if the passed point is enclosed in the handles of this Object.
Parameters:
x - x-coordinate of the point
y - y-coordinate of the point
Returns:
boolean true iff the point is enclosed in the handles
Overrides:
isInside in class GraphUnit
