Constructor Detail

HexagonImpl

public HexagonImpl(double minX,
                   double minY,
                   double sideLen,
                   HexagonOrientation orientation,
                   CoordinateReferenceSystem crs)

Creates a new hexagon.

Parameters:

minX - the min X ordinate of the bounding rectangle

minY - the min Y ordinate of the bounding rectangle

sideLen - the side length

orientation - either Hexagon.Orientation.FLAT or Hexagon.Orientation.ANGLED

crs - the coordinate reference system (may be null)
