new_allocator public member functionsnew_allocator() noexcept;
Default constructor Never throws
new_allocator(const new_allocator &) noexcept;
Constructor from other new_allocator. Never throws
new_allocator & operator=(const new_allocator &) noexcept;
Copy assignment operator from other new_allocator. Never throws
template<typename T2> new_allocator(const new_allocator< T2 > &) noexcept;
Constructor from related new_allocator. Never throws
pointer allocate(size_type count);
Allocates memory for an array of count elements. Throws bad_alloc if there is no enough memory
void deallocate(pointer ptr, size_type n) noexcept;
Deallocates previously allocated memory. Never throws
size_type max_size() const noexcept;
Returns the maximum number of elements that could be allocated. Never throws
new_allocator friend functionsvoid swap(new_allocator &, new_allocator &) noexcept;
Swaps two allocators, does nothing because this new_allocator is stateless
bool operator==(const new_allocator &, const new_allocator &) noexcept;
An new_allocator always compares to true, as memory allocated with one instance can be deallocated by another instance
bool operator!=(const new_allocator &, const new_allocator &) noexcept;
An new_allocator always compares to false, as memory allocated with one instance can be deallocated by another instance
