Empty container constructors

concurrent_map();

explicit concurrent_map( const key_compare& comp,
                         const allocator_type& alloc = allocator_type() );

explicit concurrent_map( const allocator_type& alloc );

Constructs an empty concurrent_map.

If provided, uses the comparison function object comp for all key_type comparisons and the allocator alloc to allocate the memory.

Constructors from the sequence of elements

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

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

Constructs the concurrent_map, which contains the elements from the half-open interval [first, last).

If the range [first, last) contains multiple elements with equal keys, it is unspecified which element would be inserted.

If provided, uses the comparison function object comp for all key_type comparisons and the allocator alloc to allocate the memory.

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

---

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

Equivalent to concurrent_map(init.begin(), init.end(), comp, alloc).

---

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

Equivalent to concurrent_map(init.begin(), init.end(), alloc).

Copying constructors

concurrent_map( const concurrent_map& other );

concurrent_map( const concurrent_map& 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_map( concurrent_map&& other );

concurrent_map( concurrent_map&& other, const allocator_type& alloc );

Constructs a concurrent_map 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_map();

Destroys the concurrent_map. 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_map& operator=( const concurrent_map& 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_map& operator=( concurrent_map&& other );

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.

---

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

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

If init contains multiple elements with equal keys, it is unspecified which element would be inserted.

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

Returns: a reference to *this.
