ArraySlice< T, N, Reverse, Const > Class Template Reference

#include <AH/Containers/Array.hpp>

Detailed Description

template<class T, size_t N, bool Reverse = false, bool Const = true>
class AH::ArraySlice< T, N, Reverse, Const >

Class for a view on a slice of an array.

Doesn't copy the contents of the array, it's just a reference to the original array.

Template Parameters

T	The type of elements of the Array.
N	The size of the slice.
Reverse	Whether the slice is reversed or not.
Const	Whether to save a read-only or mutable reference to the Array.
