std::experi...ic_allocator(3)

✨ std::experi...ic_allocator(3) ✨

okay bestie, welcome to the C++ Standard Libary manual page for std::experi...ic_allocator(3) — yes, the manual name is spelled Libary right there in the header, and we are keeping it exactly, no cap. 💅🦋

This is the group chat where allocator lore gets cute but stays factual. periodt. ✨

💖 NAME 💖

• std::experimental::pmr::polymorphic_allocator - std::experimental::pmr::polymorphic_allocator

(yes, the NAME line is literally the same thing twice, and we're not erasing that iconic duplication, bestie.)

🌸 Synopsis 🌸

Defined in header <experimental/memory_resource>
template< class T >                               (library fundamentals TS)
class polymorphic_allocator;

The class template std::experimental::pmr::polymorphic_allocator is an Allocator whose allocation behavior depends on the memory resource it is constructed with. so like, different instances of polymorphic_allocator can exhibit entirely different allocation behavior — highkey unhinged in the best way. this runtime polymorphism allows objects using polymorphic_allocator to behave as if they used different allocator types at run time despite the identical static allocator type. slay. ✨

🦋 Member types 🦋

• value_type — member type definition: T

💅 Member functions 💅

• constructor — constructs a polymorphic_allocator (public member function)
• destructor — implicitly declared destructor (implicitly declared) (public member function)
• operator= — copy assignment operator (public member function)

🌈 Public member functions 🌈

• allocate — allocate memory (public member function)
• deallocate — deallocate memory (public member function)
• construct — constructs an object in allocated storage (public member function)
• destroy — destroys an object in allocated storage (public member function)
• select_on_container_copy_construction — create a new polymorphic_allocator for use by a container's copy constructor (public member function)
• resource — returns a pointer to the underlying memory resource (public member function)

🌟 Non-member functions 🌟

• operator== — compare two polymorphic_allocators (function)
• operator!= — (function)
