Detailed Description

template<typename T>
class PHX::MDFieldIterator< T >

Iterate over entries of an MDField<DataT>, a runtime MDField.

This iterator is one way to replace usage of the deprecated operator[]. Regardless of underlying implementation details, iteration proceeds so that in A(i,j,k), k is the fastest index and i is the slowest one.

Example usage:

int i = 0;
for (PHAL::MDFieldIterator<ScalarT> d(array); ! d.done() ; ++d, ++i)
  *d = val[i];
