ForAllThisBNN (T,b,ns,nc)



Documentation

The ForAllThisBNN(T,b,ns,nc) macro is intended to facilitate efficient looping over the contents of BaseFabs and objects derived from BaseFab. Special attention has been paid to make it work efficiently on vector supercomputers.

This macro performs the loop over the current object (*this) where the loop runs over the points in the Box b and over components starting at ns and ending at ns+nc-1. The first argument of the macro is a type: the type contained in the BaseFab that is being iterated over. The reference variable is thisR.

For example:

template<class T> void BaseFab<T>::performSetVal (const T val, const Box bx, int ns, int num) assert(domain.contains(bx)); ForAllThisBNN(T,bx,ns,num) thisR = val; } EndFor }

Looping macro mnemonics:

This stands for the current object C for a const X stands for a BaseFab B for a Box N for an int
