Detailed Description

   template<typename _Tp, typename _Alloc = std::allocator<_Tp>>class std::deque< _Tp, _Alloc >
       A standard container using fixed-size memory allocation and constant-time manipulation of
       elements at either end.

       Meets the requirements of a container, a reversible container, and a sequence, including
       the optional sequence requirements.

       In previous HP/SGI versions of deque, there was an extra template parameter so users could
       control the node size. This extension turned out to violate the C++ standard (it can be
       detected using template template parameters), and it was removed.

       Here's how a deque<Tp> manages memory. Each deque has 4 members:

       · Tp** _M_map

       · size_t _M_map_size

       · iterator _M_start, _M_finish

       map_size is at least 8. map is an array of map_size pointers-to-'nodes'. (The name map has
       nothing to do with the std::map class, and 'nodes' should not be confused with std::list's
       usage of 'node'.)

       A 'node' has no specific type name as such, but it is referred to as 'node' in this file.
       It is a simple array-of-Tp. If Tp is very large, there will be one Tp element per node
       (i.e., an 'array' of one). For non-huge Tp's, node size is inversely related to Tp size:
       the larger the Tp, the fewer Tp's will fit in a node. The goal here is to keep the total
       size of a node relatively small and constant over different Tp's, to improve allocator
       efficiency.

       Not every pointer in the map array will point to a node. If the initial number of elements
       in the deque is small, the /middle/ map pointers will be valid, and the ones at the edges
       will be unused. This same situation will arise as the map grows: available map pointers,
       if any, will be on the ends. As new nodes are created, only a subset of the map's pointers
       need to be copied 'outward'.

       Class invariants:

       · For any nonsingular iterator i:

         · i.node points to a member of the map array. (Yes, you read that correctly: i.node does
           not actually point to a node.) The member of the map array is what actually points to
           the node.

         · i.first == *(i.node) (This points to the node (first Tp element).)

         · i.last == i.first + node_size

         · i.cur is a pointer in the range [i.first, i.last). NOTE: the implication of this is
           that i.cur is always a dereferenceable pointer, even if i is a past-the-end iterator.

       · Start and Finish are always nonsingular iterators. NOTE: this means that an empty deque
         must have one node, a deque with <N elements (where N is the node buffer size) must have
         one node, a deque with N through (2N-1) elements must have two nodes, etc.

       · For every node other than start.node and finish.node, every element in the node is an
         initialized object. If start.node == finish.node, then [start.cur, finish.cur) are
         initialized objects, and the elements outside that range are uninitialized storage.
         Otherwise, [start.cur, start.last) and [finish.first, finish.cur) are initialized
         objects, and [start.first, start.cur) and [finish.cur, finish.last) are uninitialized
         storage.

       · [map, map + map_size) is a valid, non-empty range.

       · [start.node, finish.node] is a valid range contained within [map, map + map_size).

       · A pointer in the range [map, map + map_size) points to an allocated node if and only if
         the pointer is in the range [start.node, finish.node].

       Here's the magic: nothing in deque is 'aware' of the discontiguous storage!

       The memory setup and layout occurs in the parent, _Base, and the iterator class is
       entirely responsible for 'leaping' from one node to the next. All the implementation
       routines for deque itself work only through the start and finish iterators. This keeps the
       routines simple and sane, and we can use other standard algorithms as well.

   template<typename _Tp, typename _Alloc = std::allocator<_Tp>> std::deque< _Tp, _Alloc >::deque
       (const allocator_type &__a) [inline, explicit]
       Creates a deque with no elements. Parameters:
           a An allocator object.

       Definition at line 698 of file stl_deque.h.

   template<typename _Tp, typename _Alloc = std::allocator<_Tp>> std::deque< _Tp, _Alloc >::deque
       (size_type__n, const value_type &__value = value_type(), const allocator_type &__a =
       allocator_type()) [inline, explicit]
       Creates a deque with copies of an exemplar element. Parameters:
           n The number of elements to initially create.
           value An element to copy.
           a An allocator.

       This constructor fills the deque with n copies of value.

   template<typename _Tp, typename _Alloc = std::allocator<_Tp>> std::deque< _Tp, _Alloc >::deque
       (const deque< _Tp, _Alloc > &__x) [inline]
       Deque copy constructor. Parameters:
           x A deque of identical element and allocator types.

       The newly-created deque uses a copy of the allocation object used by x.

   template<typename _Tp, typename _Alloc = std::allocator<_Tp>> std::deque< _Tp, _Alloc >::deque
       (deque< _Tp, _Alloc > &&__x) [inline]
       Deque move constructor. Parameters:
           x A deque of identical element and allocator types.

       The newly-created deque contains the exact contents of x. The contents of x are a valid,
       but unspecified deque.

   template<typename _Tp, typename _Alloc = std::allocator<_Tp>> std::deque< _Tp, _Alloc >::deque
       (initializer_list< value_type >__l, const allocator_type &__a = allocator_type()) [inline]
       Builds a deque from an initializer list. Parameters:
           l An initializer_list.
           a An allocator object.

       Create a deque consisting of copies of the elements in the initializer_list l.

       This will call the element type's copy constructor N times (where N is l.size()) and do no
       memory reallocation.

       Definition at line 750 of file stl_deque.h.

   template<typename _Tp, typename _Alloc = std::allocator<_Tp>> template<typename _InputIterator
       > std::deque< _Tp, _Alloc >::deque (_InputIterator__first, _InputIterator__last, const
       allocator_type &__a = allocator_type()) [inline]
       Builds a deque from a range. Parameters:
           first An input iterator.
           last An input iterator.
           a An allocator object.

       Create a deque consisting of copies of the elements from [first, last).

       If the iterators are forward, bidirectional, or random-access, then this will call the
       elements' copy constructor N times (where N is distance(first,last)) and do no memory
       reallocation. But if only input iterators are used, then this will do at most 2N calls to
       the copy constructor, and logN memory reallocations.

   template<typename _Tp, typename _Alloc = std::allocator<_Tp>> std::deque< _Tp, _Alloc
       >::~deque () [inline] The dtor only erases the elements, and note that if the elements
       themselves are pointers, the pointed-to memory is not touched in any way. Managing the
       pointer is the user's responsibility.

Member Function Documentation

   template<typename _Tp , typename _Alloc > void deque::_M_fill_initialize (const value_type
       &__value) [protected]
       Fills the deque with copies of value. Parameters:
           value Initial value.

       Returns:
           Nothing.

       Precondition:

   template<typename _Tp, typename _Alloc = std::allocator<_Tp>> void std::deque< _Tp, _Alloc
       >::assign (size_type__n, const value_type &__val) [inline]
       Assigns a given value to a deque. Parameters:
           n Number of elements to be assigned.
           val Value to be assigned.

       This function fills a deque with n copies of the given value. Note that the assignment
       completely changes the deque and that the resulting deque's size is the same as the number
       of elements assigned. Old data may be lost.
