    • getGeometryId

      public short getGeometryId()
      Description copied from interface: Geometry
      Returns the geometry class id. This method is useful for geometry serialization.
      Specified by:
      getGeometryId in interface Geometry
      Returns:
      the geometry id.

    • getGeometryType

      public int getGeometryType()
      Description copied from interface: Geometry

      Specified by:
      getGeometryType in interface Geometry
      Returns:
      the geometry type.
      See Also:

    • getCenteredPoint

      public Point getCenteredPoint()
      Description copied from interface: Geometry
      This method returns a point that is typically centered on the geometry. If the geometry is a point, the point is returned. If it is a line, a point on the curve interpolated at 50% is returned. If the geometry is a surface, the centroid is returned if it is inside the polygon, if not, a point inside the polygon (but likely not exactly in the center) will be returned. If the geometry is a collection, the method is called on the first part of the collection.
      Specified by:
      getCenteredPoint in interface Geometry
      Returns:
      a point likely at the center of the geometry
