drawArrow

public static void drawArrow(java.awt.Graphics g,
                             int x1,
                             int y1,
                             int x2,
                             int y2,
                             boolean start,
                             boolean end,
                             double place)

Draws line with arrow heads at either end. Location of the arrowheads along the line is controlled by the place parameter (for example, if place = 0.45, arrowheads would be placed at spots 45% away from their respective ends)

Parameters:

g - The graphics world to draw in

x1-y2 - Coords of the line

start - Arrowhead at start

end - Arrowhead at end

place - A double [0-1] indicating the line length percentage (from start) at which the arrow tip will be placed.

drawArrowhead

public static void drawArrowhead(java.awt.Graphics g,
                                 int x1,
                                 int y1,
                                 int x2,
                                 int y2)

Just draws an arrowhead at the end

Parameters:

g - The graphics world to draw in

x1-y2 - Coords of the line

start - Arrowhead at start

end - Arrowhead at end

drawArrow

public static void drawArrow(java.awt.Graphics g,
                             int x1,
                             int y1,
                             int x2,
                             int y2,
                             double place)

Draws a line with an arrowhead at its end (x2,y2) adjusted by place

Parameters:

g - The graphics world to draw in

x1-y2 - Coords of the line

place - A double [0-1] indicating the line length percentage (from start) at which the arrow tip will be placed.

Parameters:

g - The graphics world to draw in

x1-y2 - Coords of the line
