STD::NEGATE(3)
π NAME π
std::negate< _Tp > β bestie, it's one of the math functors. That's it, that's the whole job description. π
β¨ SYNOPSIS β¨
#include <functional>
Inherits std::unary_function< _Tp, _Tp >. Yeah babe, it's giving legacy inheritance, we love a family tree. πΈ
π«Ά Public Types
typedef _Tpargument_typeβ this is the type of the argument, no cap. It's literally what you feed in.typedef _Tpresult_typeβ and this is the return type, aka what you get back. π¦
π Public Member Functions
constexpr _Tp operator() (const _Tp &__x) const
That's the one, that's the whole move. constexpr, takes a const ref, hands you back a _Tp. Iconic behaviour. π
π₯ Detailed Description π₯
template<typename _Tp>
struct std::negate< _Tp >
"One of the math functors." β direct quote, they said it, not me. It's a template struct, _Tp is your type parameter, and honestly? It just does its little math thing. Main character energy, lowkey. π
π Member Typedef Documentation π
typedef _Tp std::unary_function< _Tp, _Tp >::argument_type [inherited]
argument_type is the type of the argument. (Yes, inherited β she got it from her parent class, as one does. π§)
typedef _Tp std::unary_function< _Tp, _Tp >::result_type [inherited]
result_type is the return type. Same inherited situation, same slay. β
Not me telling you twice that these are inherited β but fr fr, both typedefs come from std::unary_function< _Tp, _Tp >, and both are documented as inherited. Respect the lineage. π
π Author π
Generated automatically by Doxygen for libstdc++ from the source code. So technically no human wrote this, the machine did, and it ate. π
Okay bestie, that's the whole page, go forth and negate things (mathematically) π
Sign-off vibes: this came from the libstdc++ manual, page std::negate< _Tp >(3), and it's Doxygen-generated from the source code, so if anything's cursed, blame the source, not me. π«Ά
