Method Details

buildShape

public void buildShape(EdgeGraphicAttribute edgeAttr,
NodeShape sourceShape,
NodeShape targetShape)
                throws ShapeNotFoundException

This method sets all necessary properties of an edge using the values contained within the CollectionAttribute (like coordinates etc.). It also uses information about ports. It attaches arrows if there are any.

Specified by:

buildShape in interface EdgeShape

Specified by:

buildShape in class LineEdgeShape

Parameters:

edgeAttr - the attribute that contains all necessary information to construct a line.

sourceShape - DOCUMENT ME!

targetShape - DOCUMENT ME!

Throws:

ShapeNotFoundException - DOCUMENT ME!

contains

public boolean contains(double x,
double y)

Returns true if the edge has been hit.

Specified by:

contains in interface Shape

Specified by:

contains in class LineEdgeShape

Parameters:

x - x coordinate relative to the coordinates of this shape.

y - y coordinate relative to the coordinates of this shape.

Returns:

true if the edge has been hit else false.

getIndexOfPathWhichContains

public int getIndexOfPathWhichContains(double x,
double y)

setCoordinateSystem

public void setCoordinateSystem(CoordinateSystem coordinates)

getXexcess

public double getXexcess()

getYexcess
