Detailed Description

template<class T>
class MiniIVFAB< T >

MiniIVFAB is a templated data holder defined at the VoFs of an irregular domain.

Implemented as just a raw vector of vofs and data, more optimized for smaller memory footprint and faster linearIn/linearOut. will be more brutal for vof-by-vof indexing. bvs

Constructor & Destructor Documentation

template<class T>
MiniIVFAB< T >::MiniIVFAB (  )  [inline]

Null constructor.

template<class T>
MiniIVFAB< T >::MiniIVFAB ( const IntVectSet &  a_region,
const EBGraph &  a_ebgraph,
const int &  a_nvarin 
) [inline]

Defining constructor. Specifies the irregular domain and the number of data components per VoF. The irregular domain must lie completely within the EBGraph. The contents are uninitialized. Calls full define function.

References MiniIVFAB< T >::define().

template<class T>
MiniIVFAB< T >::MiniIVFAB ( const Interval &  a_comps,
MiniIVFAB< T > &  a_original 
) [inline]

This aliased MiniIVFAB will have a_comps.size() components, starting at zero.

template<class T>
void MiniIVFAB< T >::define ( const IntVectSet &  a_region,
const EBGraph &  a_ebgraph,
const int &  a_nvarin 
) [inline, virtual]

Full define function. Specifies the irregular domain and the number of data components per VoF. The irregular domain must lie completely within the EBGraph. The contents are uninitialized. If it has previously been defined, the old definition data is overwritten and lost.
