Constructor & Destructor Documentation

NWOQuadCFInterp::NWOQuadCFInterp ( ) [inline]

Default constructor.

Object requires define() to be called before all other functions.

References m_defined.

NWOQuadCFInterp::NWOQuadCFInterp	(	const DisjointBoxLayout &	a_thisDisjointBoxLayout,
		const DisjointBoxLayout &	a_coarserDisjointBoxLayout,
		const int &	a_numStates,
		const ProblemDomain &	a_coarseDomain,
		const int &	a_refineCoarse,
		const int &	a_interpRadius
	)			`[inline]`

Full constructor.

Parameters:

a_thisDisjointBoxLayout	layout at this level
a_coarserDisjointBoxLayout	layout at coarser level
a_numStates	number of variables
a_coarseDomain	problem domain on the coarser level
a_refineCoarse	refinement ratio between this level and the coarser level
a_interpRadius	number of layers of ghost cells to fill by interpolation

References define().

NWOQuadCFInterp::~NWOQuadCFInterp ( ) [inline]

Destructor.

Destroys all objects created by define(). Passed in data references of define() are left alone.
