Detailed Description

template<typename Scalar>
struct slp::detail::IfElseExpression< Scalar >

Derived expression type for if_else().

Returns t if cond(a, b) is true, otherwise f.

Template Parameters

Scalar Scalar type.

Constructor & Destructor Documentation

template<typename Scalar >

constexpr slp::detail::IfElseExpression< Scalar >::IfElseExpression	(	bool(*)(Scalar a, Scalar b)	cond,
		ExpressionPtr< Scalar >	a,
		ExpressionPtr< Scalar >	b,
		ExpressionPtr< Scalar >	t,

	)

inlineconstexpr

Constructs an if-else expression.

Parameters

cond	Condition evaluated on a and b.
a	The condition's first argument.
b	The condition's second argument.
t	Value selected when cond(a, b) is true.
f	Value selected when cond(a, b) is false.
