[Repast-developer] one bug in the class of uchicago.src.sim.gis.LineStringAdapter?

[yy <yon...@so...>]

dear all,

I want to develop some GIS functions in the Repast frame. When I try to =
display multilinestring in GisDisplay, I find one bug in the class of =
uchicago.src.sim.gis.LineStringAdapter.(It seems there is no =
MultiLineStringAdapter in the gis package)

the bug is in the function of setGeometry(Geometry geo).
the code is as following:
*************************************************************************=
*******************************************************************
public void setGeometry(Geometry geo){
       if(!geo.getGeometryType().toLowerCase().equals("linestring") &&
                =
!(geo.getGeometryType().toLowerCase().equals("multilinestring"))){
            throw new IllegalArgumentException("This is not a =
linestring, it is a " + geo.getGeometryType());
        }
        if(geo.getGeometryType().toLowerCase().startsWith("multi")){
            multi =3D true;
        }
        LineString line =3D (LineString) geo;
        super.setFrom(new PointAdapter(line.getStartPoint()));
        super.setTo(new PointAdapter(line.getEndPoint()));
        Coordinate[] coords =3D line.getCoordinates();
        points =3D new LinePoint[coords.length];
        points[0] =3D new LinePoint(coords[0]);
        points[0].setToPoint(points[1]);
        if (points.length < 3) {
            points[1] =3D new LinePoint(coords[1]);
            points[1].setFromPoint(points[0]);
            strength +=3D GisUtilities.getDistance(coords[0], =
coords[1]);
        } else {
            for (int i =3D 1; i < coords.length - 1; i++) {
                points[i] =3D new LinePoint(coords[i]);
                strength +=3D GisUtilities.getDistance(coords[i], =
coords[i - 1]);
                points[i].setFromPoint(points[i - 1]);
                points[i].setToPoint(points[i + 1]);
            }
            points[points.length - 1] =3D new =
LinePoint(coords[points.length - 1]);
            points[points.length - 1].setFromPoint(points[points.length =
- 2]);
            strength +=3D GisUtilities.getDistance(coords[points.length =
- 1], coords[points.length - 2]);
        }
}
*************************************************************************=
*************************************************************************=
******
at first, this code judge if this geometry is a linestring or =
multilingstring or even neither, if this is a multiline, the multi sign =
will be set to be true, all these are right.
but then it try to force the geo to be a lineString without any =
judgement. When I use this function, my geo is a multiLineString, so =
there will be Exception thrown.
This error are so obvious that I donot sure if this can be called a bug. =


thank you very much!

cheers,
