__gnu_pbds...ate_policy(3)

💖 __gnu_pbds::sample_update_policy 💖

okay bestie, welcome to the Library Functions Manual — yes this is a real manpage, yes it's from libstdc++, and yes we're gonna get through it together. this one's about a lil class called sample_update_policy. it's a sample list-update policy. that's the whole vibe. let's go 🦋

---

✨ NAME ✨

__gnu_pbds::sample_update_policy — a sample list-update policy, periodt.

---

✨ SYNOPSIS ✨

#include <sample_update_policy.hpp>

🌸 Public Member Functions

• sample_update_policy() — default constructor, no thoughts, just vibes.
• sample_update_policy(const sample_update_policy &) — copy constructor, it's giving "twin where have you been".
• void swap(sample_update_policy &other) — swaps content. trading places, lowkey iconic.

🌸 Protected Types

• typedef some_metadata_type metadata_type — the metadata that this functor operates on. protected, so it's iykyk only.

🌸 Protected Member Functions

• metadata_type operator()() const — creates a metadata object. baby metadata born.
• bool operator()(metadata_reference) const — decides whether a metadata object should be moved to the front of the list. a list-update based containers object will call this method to decide whether to move a node to the front of the list. the method shoule return true if the node should be moved to the front of the list. (yes bestie, "shoule" — that's what it says, I don't make the rules 💀)

---

✨ Detailed Description ✨

A sample list-update policy. that's it. that's the whole description. short queen. 👑

---

✨ Member Typedef Documentation ✨

💜 typedef some_metadata_type __gnu_pbds::sample_update_policy::metadata_type

[protected]

Metadata on which this functor operates. it's protected so don't go poking at it from outside, we respect boundaries in this house 🫶

✨ Constructor & Destructor Documentation ✨

💜 __gnu_pbds::sample_update_policy::sample_update_policy()

Default constructor.

Referenced by sample_update_policy(), and swap(). so it's out here being referenced by itself and by swap() — main character energy fr fr ✨

💜 __gnu_pbds::sample_update_policy::sample_update_policy(const sample_update_policy &)

Copy constructor.

References sample_update_policy(). it literally references its own default constructor, that's so self-aware of it 💅

---

✨ Member Function Documentation ✨

💜 metadata_type __gnu_pbds::sample_update_policy::operator()() const

[protected]

Creates a metadata object. that's the job. one job. does it well. 🌟

💜 bool __gnu_pbds::sample_update_policy::operator()(metadata_reference) const

[protected]

Decides whether a metadata object should be moved to the front of the list. A list-update based containers object will call this method to decide whether to move a node to the front of the list. The method shoule return true if the node should be moved to the front of the list.

so real talk: you get handed a metadata_reference, you look at it, and you go "bestie... front of the list? yes or no?" return true and the node gets bumped to the front. return not-true and it stays where it is. that's the whole decision-making arc. no cap. 🔥

💜 void __gnu_pbds::sample_update_policy::swap(sample_update_policy &other)

[inline]

Swaps content.

References sample_update_policy(). inline, because it's efficient like that. slay.
