# Construction, destruction, copying

## Empty container constructors

>     concurrent_vector();

>     explicit concurrent_vector( const allocator_type& alloc );

> Constructs an empty `concurrent_vector`.

> If provided, uses the allocator `alloc` to allocate the memory.

## Constructors from the sequence of elements

>     explicit concurrent_vector( size_type count, const value_type& value,
>                                 const allocator_type& alloc = allocator_type() );

> Constructs a `concurrent_vector` containing `count` copies of the `value` using the allocator `alloc`.

>     explicit concurrent_vector( size_type count,
>                                 const allocator_type& alloc = allocator_type() );

> Constructs a `concurrent_vector` containing `n` default constructed in-place elements using the allocator `alloc`.

>     template <typename InputIterator>
>     concurrent_vector( InputIterator first, InputIterator last,
>                        const allocator_type& alloc = allocator_type() );

> Constructs a `concurrent_vector` contains all elements from the half-open interval `[first, last)` using the allocator `alloc`.

> Requirements: the type `InputIterator` must meet the requirements of `InputIterator` from the [input.iterators] ISO C++ Standard section.

>     concurrent_vector( std::initializer_list<value_type> init,
>                        const allocator_type& alloc = allocator_type() );

> Equivalent to `concurrent_vector(init.begin(), init.end(), alloc)`.

## Copying constructors

>     concurrent_vector( const concurrent_vector& other );

>     concurrent_vector( const concurrent_vector& other,
>                        const allocator_type& alloc );

> Constructs a copy of `other`.

> If the allocator argument is not provided, it is obtained by calling `std::allocator_traits<allocator_type>::select_on_container_copy_construction(other.get_allocator())`.

> The behavior is undefined in case of concurrent operations with `other`.

## Moving constructors

>     concurrent_vector( concurrent_vector&& other );

>     concurrent_vector( concurrent_vector&& other,
>                        const allocator_type& alloc );

> Constructs a `concurrent_vector` with the contents of `other` using move semantics.

> `other` is left in a valid, but unspecified state.

> If the allocator argument is not provided, it is obtained by calling `std::move(other.get_allocator())`.

> The behavior is undefined in case of concurrent operations with `other`.

## Destructor

>     ~concurrent_vector();

> Destroys the `concurrent_vector`. Calls destructors of the stored elements and deallocates the used storage.

> The behavior is undefined in case of concurrent operations with `*this`.

## Assignment operators

>     concurrent_vector& operator=( const concurrent_vector& other );

> Replaces all elements in `*this` by the copies of the elements in `other`.

> Copy-assigns allocators if `std::allocator_traits<allocator_type>::propagate_on_container_copy_assignment::value` is `true`.

> The behavior is undefined in case of concurrent operations with `*this` and `other`.

> Returns: a reference to `*this`.

>     concurrent_vector& operator=( concurrent_vector&& other ) noexcept(/*See below*/);

> Replaces all elements in `*this` by the elements in `other` using move semantics.

> `other` is left in a valid, but unspecified state.

> Move assigns allocators if `std::allocator_traits<allocator_type>::propagate_on_container_move_assignment::value` is `true`.

> The behavior is undefined in case of concurrent operations with `*this` and `other`.

> Returns: a reference to `*this`.

> Exceptions: `noexcept` specification:

> >     noexcept(std::allocator_traits<allocator_type>::propagate_on_container_move_assignment::value ||
> >              std::allocator_traits<allocator_type>::is_always_equal::value)

>     concurrent_vector& operator=( std::initializer_list<value_type> init );

> Replaces all elements in `*this` by the elements in `init`.

> The behavior is undefined in case of concurrent operations with `*this`.

> Returns: a reference to `*this`.

## assign

>     void assign( size_type count, const value_type& value );

> Replaces all elements in `*this` by `count` copies of `value`.

>     template <typename InputIterator>
>     void assign( InputIterator first, InputIterator last );

> Replaces all elements in `*this` by the elements from the half-open interval `[first, last)`.

> This overload only participates in overload resolution if the type `InputIterator` meets the requirements of InputIterator from the [input.iterators] ISO C++ Standard section.

>     void assign( std::initializer_list<value_type> init );

> Equivalent to `assign(init.begin(), init.end())`.

## get_allocator

>     allocator_type get_allocator() const;

> Returns: a copy of the allocator associated with `*this`.
