Detailed Description

template<unsigned int N>
class CxxUtils::ArrayIteratorChooser< N >

Helper for defining iterators over Array's.

Helper for defining iterators over Array's, specialized for N == 1.

For Array<N> with N >= 2, we want to use ArrayIterator<N> as the iterator class. However, for Array<1>, we want to use just an Arrayelt*. I'm too lazy to either specialize ArrayIterator<1> or to add a new Array<1> specialization. So this is an easier way of achieving the same effect. Array<N> uses as its iterator type ArrayIteratorChooser<N>::const_iterator; this small class then gets specialized for == 1. We also need to provide a way to create the iterators (since it will be done differently in the two cases). This is supplied by the make_iterator method.

For N == 1, we specialize so that Array<N> uses Arrayelt* as its iterator type.
