std::pmr::p...c_allocator(3) C++ Standard Libary std::pmr::p...c_allocator(3) NAME std::pmr::polymorphic_allocator::polymorphic_allocator - std::pmr::polymorphic_allocator::polymorphic_allocator Synopsis polymorphic_allocator() noexcept; (1) polymorphic_allocator( const polymorphic_allocator& other ) = de- fault; (2) template< class U > (3) polymorphic_allocator( const polymorphic_allocator<U>& other ) noex- cept; polymorphic_allocator( std::pmr::memory_resource* r ); (4) Constructs a new polymorphic_allocator. 1) Constructs a polymorphic_allocator using the return value of std::pmr::get_default_resource() as the underlying memory resource. 2-3) Constructs a polymorphic_allocator using other.resource() as the underlying memory resource. 4) Constructs a polymorphic_allocator using r as the underlying mem- ory resource. This constructor provides an implicit conversion from std::pmr::mem- ory_resource*. Parameters other - another polymorphic_allocator to copy from r - pointer to the memory resource to use. May not be null. Exceptions 4) Throws nothing. Notes Copying a container using a polymorphic_allocator will not call the allocator's copy constructor. Instead, the new container will use the return value of select_on_container_copy_construction (a default-constructed poly- morphic_allocator) as its allocator.
