std::experimental::const_where_expression

Template:cpp/experimental/simd/const where expression/navbar content

 

Defined in header <experimental/simd>
template < class M, class V > class const_where_expression;

The class template const_where_expression abstracts the notion of selected elements of a given const object of arithmetic or data-parallel type. Selected elements signifies the elements data[i] for all i ∈ {j ∈ ℕ0 | j < M::size() ⋀ mask[j]}.

Template parameters

M	-	The mask type
V	-	The value type M applies on

Valid combinations of (M, V) are: (simd_mask<T, Abi>, const simd<T, Abi>), (simd_mask<T, Abi>, const simd_mask<T, Abi>), (bool, const T).

Member functions

operator-	negates selected elements (public member function)
copy_to	stores selected elements to address (public member function)
