template < class T, class Abi >

const_where_expression<simd_mask<T, Abi>, const simd_mask<T,
Abi>> (4) (parallelism TS v2)
where( const nodeduce_t<simd_mask<T, Abi>>& mask,

const simd_mask<T, Abi>& value) noexcept;
template < class T >

where_expression<bool, T> (5) (parallelism TS v2)

where( /*see below*/ mask, T& value ) noexcept;
template < class T >

const_where_expression<bool, const T> (6) (parallelism TS v2)

where( /*see below*/ mask, const T& value ) noexcept;

Constructs a new const_where_expression or where_expression.

1-6) constructs a where_expression from given mask and value parameters.

Parameters¶

1-4)

mask - the simd_mask object
value - reference to the object that mask applies on

5-6)

mask - the mask of type bool
value - reference to the scalar that mask applies on

Return value¶

The constructed const_where_expression or where_expression.

Notes¶

5-6) uses implementation defined type of mask, so that implicit conversions from
other types to bool is disabled.
