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.
