Detailed Description

Order permutator. Generates all permutations of orders from a set defined by a range of orders.

Used to generate all possible generation of horizontal and vertical orders bettween the starting order and the ending order. Both the starting order and the ending order are included.

Suggested Use

      OrderPermutator order_perm(start_order, end_order, false);
      do {
        int order_h = order_perm.get_order_h();
      } while (order_perm.next());

Constructor & Destructor Documentation

RefinementSelectors::OrderPermutator::OrderPermutator	(	int	start_quad_order = `0`,
		int	end_quad_order = `0`,
		bool	iso_p = `false`,
		int *	tgt_quad_order = `NULL`
	)

Constructor.

Parameters:

`[in]`	start_quad_order	The starting order in an encoded form.
`[in]`	end_quad_order	The ending order in an encoded form.
`[in]`	iso_p	True if both orders (i.e. horizontal and vertical) should be increased simultaneously.
`[in]`	tgt_quad_order	A point to a location to which a current orders (i.e. horizontal and vertical) are stored in an encoded form. Ignored if NULL.
