Class figPac.fParticleLine 

java.lang.Object
   |
   +----figPac.fParticleLine
public class fParticleLine
extends Object
implements fElement, S2V, fInteractive, MouseListener, MouseMotionListener
Each instance of the class fParticleLine represents a Feynman diagram particle line. This is an arc of a parabolic curve with a specified starting point, ending point and height (maximum distance from the straight line segment joining the ends). As well there is an arrowhead indictaing the orientation of the line.

Variable Index

o arrowfrac
The fraction of the way along the line that the arrowhead appears.
o arrowhead
The arrowhead on the particle line.
o from
The starting point of the line in user coordinates.
o height
The height of the line (maximum distance from the straight line segment joining the ends) in usr coordinates.
o parabola
The curve part of the the particle line.
o to
The end point of the line in user coordinates.

Constructor Index

o fParticleLine()
o fParticleLine(double, double, double, double)
Creates a particle line with initial point (x1,y1) and final point (x2,y2), both in user coordinates.
o fParticleLine(double, double, double, double, double, double)
Creates a particle line with initial point (x1,y1) and final point (x2,y2), both in user coordinates.
o fParticleLine(double[], double[])
Creates a particle line with initial point from[] and final point to[], both in user coordinates.
o fParticleLine(double[], double[], double, double)

Constructors

o fParticleLine 
 public fParticleLine()
o fParticleLine 
 public fParticleLine(double from[],
                      double to[])
Creates a particle line with initial point from[] and final point to[], both in user coordinates. The height is zero and the arrowhead appears in the middle of the line.

o fParticleLine 
 public fParticleLine(double x1,
                      double y1,
                      double x2,
                      double y2)
Creates a particle line with initial point (x1,y1) and final point (x2,y2), both in user coordinates. The height is zero and the arrowhead appears in the middle of the line.

o fParticleLine 
 public fParticleLine(double from[],
                      double to[],
                      double height,
                      double arrowfrac)
Creates a particle line with initial point from[] and final point to[], both in user coordinates. The height and positioning of the arrowhead are given by the last two arguments.

o fParticleLine 
 public fParticleLine(double x1,
                      double y1,
                      double x2,
