public class DotBSplineInterpolator
extends org.eclipse.gef.fx.nodes.AbstractInterpolator

A DotBSplineInterpolator is an interpolator that creates a PolyBezier geometry corresponding to a single B-spline. It expects that the start, end, and control points of the Connection it routes correspond to what can be specified through the 'pos' attribute of the edges within Graphviz DOT as follows (if multiple splines are specified through the 'pos' attribute, they have to be represented through multiple connections).

The DotBSplineInterpolator expects that the connection's control points represent control points of connected cubic Bézier segments in the form 'p, (p, p, p)+'. In case the start point equals the first control point, or the end point equals the last control point, they are ignored when constructing the B-spline. In case this is not the case, linear segments are added from the start point to the first control point and from the last control point to the end point, respectively.
