πŸ’… std::flat_m...:upper_bound(3) πŸ’…

okay bestie, welcome to the C++ Standard Libary page for std::flat_multimap::upper_bound β€” yes, that spelling is in the header, and we are keeping it πŸ’€. This one is short, cute, and extremely β€œwhere does the first bigger-than-this element live?” energy. πŸ¦‹


🌸 NAME 🌸

std::flat_multimap::upper_bound β€” std::flat_multimap::upper_bound

like… the name is the name, and honestly? iconic. πŸ‘‘


πŸ“œ Synopsis πŸ“œ

iterator upper_bound( const Key& key );             (1) (since C++23)
const_iterator upper_bound( const Key& key ) const; (2) (since C++23)
template< class K >                                 (3) (since C++23)
iterator upper_bound( const K& x );
template< class K >                                 (4) (since C++23)
const_iterator upper_bound( const K& x ) const;

So here’s the vibe check, overload by overload:

  1. Overloads 1,2 return an iterator pointing to the first element that is greater than key.
  2. Overloads 3,4 return an iterator pointing to the first element that compares greater to the value x. This overload participates in overload resolution only if the qualified-id Compare::is_transparent is valid and denotes a type. It allows calling this function without constructing an instance of Key. 🫢

no cap, that transparent-comparator bit is the little VIP pass that lets you search without making a Key first. ✨


πŸŽ€ Parameters πŸŽ€

  • key β€” key value to compare the elements to.
  • x β€” alternative value that can be compared to Key.

πŸ’– Return value πŸ’–

Iterator pointing to the first element that is greater than key. If no such element is found, past-the-end (see end()) iterator is returned. 🫑

like, if there’s no bigger one, you get the β€œend of the line” iterator, and that is very much its whole thing.


πŸ”₯ Complexity πŸ”₯

Logarithmic in the size of the container. periodt. 🌈
