  • Method Details

    • setConstrainedToCircle

      public void setConstrainedToCircle(boolean isConstrainedToCircle)
      Sets whether generated points are constrained to lie within a circle contained within each grid cell. This provides greater separation between points in adjacent cells.

      The default is to not be constrained to a circle.

      Overrides:
      setConstrainedToCircle in class org.locationtech.jts.shape.random.RandomPointsInGridBuilder
      Parameters:
      isConstrainedToCircle -

    • setGutterFraction

      public void setGutterFraction(double gutterFraction)
      Sets the fraction of the grid cell side which will be treated as a gutter, in which no points will be created. The provided value is clamped to the range [0.0, 1.0].
      Overrides:
      setGutterFraction in class org.locationtech.jts.shape.random.RandomPointsInGridBuilder
      Parameters:
      gutterFraction -
