Constructor Details

SmoothLineEdgeShape

public SmoothLineEdgeShape()

Default constructor. Used to ensure that next time buildShape is called, the bends are modified.

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. When mustExpandBends is true, i.e. it is started the very first time for an object, all line segments except the first and last ones are divided into two equally long segments. That is to ensure that the single quadric splines fit together.

Specified by:

buildShape in interface EdgeShape

Overrides:

buildShape in class QuadCurveEdgeShape

Parameters:

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