Constructor & Destructor Documentation

FourthOrderCFInterp::FourthOrderCFInterp (  )  [inline]

Default constructor.

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

References m_defined.

FourthOrderCFInterp::FourthOrderCFInterp ( 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
