Function Documentation

template<class T> void aliasLevelData (  LevelData< T > &  a_alias, LevelData< T > *  a_original, const Interval &  a_interval )

LevelData aliasing function. Parameters: a_alias  aliased LevelData<T> object. original data in a_alias is destroyed and new aliasing role assumed. a_original  pointer to LevelData<T> that will be aliased. a_interval  range of components of each T in a_original that will be created in the a_alias argument. LevelData<FArrayBox> original(dbl, 4, 2*IntVect::Unit); Interval subcomps(2, 3); LevelData<FArrayBox> alias; aliasLevelData<FArrayBox>(alias, &original, subcomps); // component 0 of every FArrayBox in alias references the same data as // component 2 in original The template class T must have an 'alias' constructor class A { public: A(const Interval& subcomps, A& original);// alias constructor ... };
