Detailed Description

template<typename T, typename U, typename V>
struct boost::proto::if_else_< T, U, V >

A metafunction for generating ternary conditional expression types, a grammar element for matching ternary conditional expressions, and a PrimitiveTransform that dispatches to the pass_through<> transform.
