NAME
std::experimental::pmr::polymorphic_allocator<T>::polymorphic_allocator - std::experimental::pmr::polymorphic_allocator<T>::polymorphic_allocator
Synopsis
polymorphic_allocator() noexcept; (1)
polymorphic_allocator( const polymorphic_allocator& other ) noexcept = default; (2)
template< class U > (3)
polymorphic_allocator( const polymorphic_allocator<U>& other ) noexcept;
polymorphic_allocator( memory_resource* r); (4)
Constructs a new polymorphic_allocator.
1) Constructs a polymorphic_allocator using the return value of std::experimental::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 memory resource. This constructor provides an implicit conversion from memory_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.
