createObject

public java.lang.Object createObject(java.lang.String str)

Create an instance of route from the String spec. Current accepted .dot file string format: For beizer curves: [x0,y0 (x11,y11 x12,y12 x13,y13)+] p0-p1-... [e|E,xe,ye x0,y0 (x11,y11 x12,y12 x13,y13)+] p0-p1-...->pe [s|S,xs,ys [e,xe,ye] x0,y0 (x11,y11 x12,y12 x13,y13)+] ps<-p0-p1-...->pe For polyline: [p x0,y0 x1,y1 ...] [p s|S,xs,ys x0,y0 x1,y1 ...] [p e|E,xs,ys x0,y0 x1,y1 ...] s=location of tail arrow head from start of spline. S=location of head arrow head from start of spline. e=location of head arrow head from end of spline. E=location of tail arrow head from end of spline. where xs,ys and xe,ye are the arrow end points away from the curve.

parsePoint

private int parsePoint(java.lang.String str,
                       int start,
                       int max,
                       com.port80.util.struct.FloatList pts)

skipWhiteSpace

private int skipWhiteSpace(java.lang.String str,
                           int start,
                           int max)

createPolyline

private DotRoute createPolyline(com.port80.util.struct.FloatList pts,
                                com.port80.util.struct.FloatList startpt,
                                com.port80.util.struct.FloatList endpt,

createBezier

private DotRoute createBezier(com.port80.util.struct.FloatList pts,
                              com.port80.util.struct.FloatList startpt,
                              com.port80.util.struct.FloatList endpt,
                              boolean isReversed)

The Bezier points from the .dot file looks like a mess. It appears to be arranged like this: 'e' x0,y0 (xn3,yn3 xn2,yn2 xn1,yn1) ... (x13,y13 x12,y12 x11,y11) x_ y_ p_<-p0->p1->...->pn 's' x_,y_ (xn3,yn3 xn2,yn2 xn1,yn1) ... (x13,y13 x12,y12 x11,y11) x0 y0 p0->p1->...->pn->p_ where p_ is the arrow head.
