◆ copy() [4/6]

void FluxBox::copy	(	const FluxBox &	a_src,
		const Box &	a_destbox
	)

Modifies this FluxBox by copying the contents of the argument src into it. A copy within the intersecting region of the domains of the two FluxBoxes and the specified Box a_destbox is performed. All components are copied.

◆ copy() [5/6]

void FluxBox::copy	(	const Box &	R,
		const Interval &	Cdest,
		const FluxBox &	src,
		const Interval &	Csrc
	)

Copies from a subsection of one box into another.

Assumes the boxes are both in the same index space, and that box R is completely contained in both the src and destination boxes. This function required by BoxLayoutData

◆ copy() [6/6]

void FluxBox::copy	(	const Box &	srcbox,
		const Interval &	destcomps,
		const Box &	destbox,
		const FluxBox &	src,
		const Interval &	srccomps
	)

Modifies this FluxBox by copying the contents of src into it.

This, the most general form of copy, specifies the contents of any sub-box srcbox in `FluxBox' src may be copied into a (possibly different) destbox in the destination `FluxBox'. Note that although the srcbox and the destbox may be disjoint, they must be the same size and shape. If the sizes differ, the copy is undefined and a runtime error results. This copy function is the only one of the copy functions to allow a copy between differing boxes. The user also specifies how many components are copied, starting at component srccomp in src and stored starting at component destcomp. The results are UNDEFINED if the src and dest FluxBoxes are the same and the srcbox and destbox overlap.

◆ negate() [1/3]

FluxBox& FluxBox::negate	(	const Box &	subbox,
		int	comp = `0`,
		int	numcomp = `1`

		int	numcomp = `1`
	)

Modifies this FluxBox to its additive inverse.

Modifies this FluxBox by replacing each value with its additive inverse, for the given range of components over the whole domain of the FluxBox. Returns *this.

◆ negate() [3/3]

FluxBox& FluxBox::negate ( )

Modifies this FluxBox to its additive inverse.

Modifies this FluxBox by replacing each value with its additive inverse for all components over the whole domain of the FluxBox. Returns *this.

The actual directionally-dependent subbox is a_subbox.surroundingNodes(dir); NOTE: a_subbox must be contained in the cell-centered Box of this FluxBox. Returns *this

Referenced by define().

◆ minus()

FluxBox& FluxBox::minus	(	const FluxBox &	a_src,
