array_view::reinterpret_as Method
Reinterprets the array_view through a one-dimensional array_view, which as an option can have a different value type than the source array_view.
template <
typename _Value_type2
>
array_view<_Value_type2, _Rank> reinterpret_as() const restrict(amp,cpu);
template <
typename _Value_type2
>
array_view<const _Value_type2, _Rank> reinterpret_as() const restrict(amp,cpu);
Parameters
- _Value_type2
The data type of the new array_view object.
Return Value
An array_view object or a const array_view object that is based on this array_view, with the element type converted from T to _Value_type2, and the rank reduced from N to 1.
Remarks
Sometimes it is convenient to view a multi-dimensional array as a linear, one-dimensional array, which may have a different value type than the source array. You can achieve this on an array_view by using this method.
Warning
Reinterpeting an array_view object by using a different value type is a potentially unsafe operation. This functionality should be used with care.
Here's an example:
struct RGB { float r; float g; float b; };
array<RGB,3> a = ...;
array_view<float,1> v = a.reinterpret_as<float>();
assert(v.extent == 3*a.extent);
