These functions will invoke error messages when invoked. C++ will ensure that constructors are not called for the base class by a user, but a 'define' function has no such protection, hence the need to prevent such usage. A runtime error is not a perfect solution...(strong construction gets around this *sigh*). classes that derive from LevelData will have to turn it's valid defines into runtime errors also and make it's own defines. Thus taking over the job of the compiler.

Member Function Documentation

template<class T>
void LevelData< T >::apply void(*)(const Box &box, int comps, T &t)  a_Function  )  [virtual]
 

User writes a function with the signature:

     void myfunction(const Box& box, int comps, T& t){ your code here;}

They can then hand this off to LayoutData::apply. This class then cycles through all the T objects and invokes this function. Function must not be inline. (I'm still trying to figure out a nice way to send in non-static member functions).

for example:

  LevelData<FArrayBox> data(layout, 3, IntVect::Unit);
  struct val{
  static void set1(const Box& box, int comps, const FArrayBox& f)
  {
    f.setVal(box, box.smallEnd(0));
  }

  data.apply(val::set1);

Data over a disjoint union of rectangles.

LevelData is-a BoxLayoutData. It is built from a DisjointBoxLayout instead though, thus making the data in a DisjointBoxLayout uniquely defined for all spatial indices defined by the underlying DisjointBoxLayout. It carries within it an inherent concept of ghost cells (which the user can choose to be empty).

Since LevelData is-a BoxLayoutData, all the methods required of the template class T for BoxLayoutData are also required for LevelData. LevelData does not have any extra requirements.
