Detailed Description

A Rectangular Domain on an Integer Lattice.

A Box is an abstraction for defining discrete rectangular regions of SpaceDim-dimensioned indexing space. Boxes have an IndexType, which defines IndexType::CELL or IndexType::NODE based points for each direction and a low and high IntVect which defines the lower and upper corners of the Box. Boxes can exist in positive and negative indexing space.

Box is a dimension dependent class, so SpaceDim must be defined as either 1, 2, or 3 when compiling.

◆ chop()

Box Box::chop	(	int	dir,
		int	chop_pnt
	)

misc

Chops the Box at the chop_pnt in the dir direction returns one Box, modifies the object Box. The union of the two is the original Box. The modified Box is the low end, the returned Box is the high end. If type(dir) = CELL, the Boxes are disjoint with the chop_pnt included in the high end (new Box). It is an ERROR if chop_pnt is the low end of the orig Box. If type(dir) = NODE, the chop_pnt is included in both Boxes but is the only point in common. It is also an error if the chop_pnt is an end node of the Box. Directions are zero-based. It is an error if not 0 <= dir < SpaceDim.

◆ degenerate()

void Box::degenerate	(	Box &	a_to,
		const SliceSpec &	a_sliceSpec,
		bool *	a_outofbounds = `0`
	)		const

Makes a_to a box that's the same as *this except that it's just one cell thick in the a_sliceSpec.direction-th direction, and its (one) coordinate in that direction is a_sliceSpec.position.

If a_sliceSpec.position is outside the range of *this, and a_outofbounds isn't null, then we set *a_outofbounds to true, otherwise to false.

It would be more natural to return a Box, than to set the value of a Box reference, but we do it this way to be consistent with BaseFab::degenerate() where we can't return an object because of the policy of disallowing copy constructors for heavyweight classes.
