Detailed Description

template<class ViewModType, class DomainType, dim_t NDim>
class dash::ViewModBase< ViewModType, DomainType, NDim >

Note

As an alternative, all view modifications could be stored in command objects of a single ViewMod type. Expressions then could not be evalated at compile-time, however.

However, View modifier types should subclass a common ViewMod base class - or vice versa, following the policy pattern with the operation specified as policy:

template <dim_t DimDiff, class DomainType>
class ViewMod : DomainType
{
// ...
}

or:

template <dim_t DimDiff, class ViewModOperation>
class ViewMod : ViewModOperation
{
// ...
}
class ViewModSubOperation;
// defines
// - sub<N>(...)
// - view_mod_op() { return sub<N>(...); }
ViewMod<0, ViewModSubOperation> view_sub(initializer_list);
// - either calls view_mod_op(initializer_list) in constructor
// - or provides method sub<N>(...) directly
Todo:
Eventually, these probably are not public definitions. Move to namespace internal. Define dereference operator*() for view types, delegating to domain::operator* recursively.
