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.
