Constructor Detail

PolygonsSet.ComparableSegment

public PolygonsSet.ComparableSegment(Vector2D start,
                                     Vector2D end,
                                     Line line)

Build a segment.

Parameters:

start - start point of the segment

end - end point of the segment

line - line containing the segment

PolygonsSet.ComparableSegment

public PolygonsSet.ComparableSegment(Vector2D start,
                                     double dx,
                                     double dy)

Build a dummy segment.

The object built is not a real segment, only the sorting key is used to allow searching in the neighborhood of a point. This is an horrible hack ...

Parameters:

start - start point of the segment

dx - abscissa offset from the start point

dy - ordinate offset from the start point
