  • Method Details

    • getDimension

      int getDimension()
      Returns the dimensionality of this boundary.
      Returns:
      0 for point, 1 for line, 2 for polygon, 3 for polyhedron

    • contains

      boolean contains(P point)
      Checks if a point is contained within this boundary.
      Parameters:
      point - the point to test
      Returns:
      true if point is inside or on the boundary

    • isEmpty

      boolean isEmpty()
      Checks if this boundary is empty.
      Returns:
      true if the boundary has no extent
