Construction, destruction, copying

Empty container constructors

concurrent_queue();

explicit concurrent_queue( const allocator_type& alloc );

Constructs empty concurrent_queue. If provided uses the allocator alloc to allocate the memory.

Constructor from the sequence of elements

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

Constructs a concurrent_queue containing all elements from the half-open interval [first, last) using the allocator alloc to allocate the memory.

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

Copying constructors

concurrent_queue( const concurrent_queue& other );

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

Constructs a copy of other.

If the allocator argument is not provided, it is obtained by 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_queue( concurrent_queue&& other );

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

Constructs a concurrent_queue with the content 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 std::move(other.get_allocator()).

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

Destructor

~concurrent_queue();

Destroys the concurrent_queue. Calls destructors of the stored elements and deallocates the used storage.

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