Constructor Detail

plotInterval

public plotInterval(double x,
                    double y,
                    double deltax,
                    double deltay,
                    double s,
                    double t,
                    fundamentals.mouseInfo info)
             throws UserException

The constructor does initialization. A zero generator vector gives a LeaRuntimeException. A degenerate interval is handled by the warner.

Parameters:

x - the first coordinate of anchor

y - the second coordinate of anchor

deltax - the first coordinate of generator

deltay - the second coordinate of generator

s - the parameter of one endpoint

t - the parameter of other endpoint

Throws:

UserException - if an error occurs

Method Detail

draw

public void draw(java.awt.Graphics g)

Draw the interval on screen.

Specified by:

draw in interface plotObject

Parameters:

g - the graphics canvas

toPs

public java.lang.String toPs()

Represent the plot object as a postscript command

Specified by:

toPs in interface plotObject

mouseVicinity

public boolean mouseVicinity(fundamentals.mouseVector mouseAt)

See if mouse position is close to this point.

Specified by:

mouseVicinity in interface plotObject

Parameters:

mouseAt - The coordinates of the mouse position

Returns:

true if the mouse is close to the point.

visiblePixel

public fundamentals.mouseVector visiblePixel(double parameter)

Specified by:

visiblePixel in interface plotObject

weight

public double weight()

Specified by:

weight in interface plotObject
