151 @ingroup macros
152 
153  The macro ForAllThisPencil(T,b,ns,nc) is intended to facilitate efficient
154  looping over the contents of BaseFabs and objects derived from BaseFab.
155  Special attention has been paid to make it work efficiently on vector
156  supercomputers.
157 
158  This macro acts upon the BaseFab *this. Instead of iterating over the
159  entire Box b, it iterates over components starting at component ns and
160  ending at component ns+nc-1, in all directions except the first coordinate
161  direction. The user must iterate over the first coordinate direction within
162  the ForAllThisPencil loop. The macro creates two internal reference
163  variables; thisR that references the first element in the pencil, and
164  thisLen that gives the length of the pencil. The first argument of the
165  macro is a type: the type contained in the BaseFab that is being iterated
166  over.
167 
168  We can rewrite the code illustrated in `ForAllThisBNN' in this form:
169 
170 \code
171  template <class T>
172  void BaseFab<T>::performSetVal(const T val, const Box bx, int ns, int nc)
173  {
174  CH_assert(domain.contains(bx));
175  ForAllThisPencil(T,bx,ns,nc)
176  {
177  T* dog = &thisR;
178  for (int i = 0; i < thisLen; i++)
179  dog[i] = val;
180  } EndForPencil
181  }
182 \endcode
