Detailed Description
template<typename _Tp, typename _Sequence = deque<_Tp>>class std::queue< _Tp, _Sequence >
A standard container giving FIFO behavior.
Meets many of the requirements of a container, but does not define anything to do with iterators. Very
few of the other standard container interfaces are defined.
This is not a true container, but an adaptor. It holds another container, and provides a wrapper
interface to that container. The wrapper is what enforces strict first-in-first-out queue behavior.
The second template parameter defines the type of the underlying sequence/container. It defaults to
std::deque, but it can be any type that supports front, back, push_back, and pop_front, such as std::list
or an appropriate user-defined type.
Members not found in 'normal' containers are container_type, which is a typedef for the second Sequence
parameter, and push and pop, which are standard queue/FIFO operations.

Constructor & Destructor Documentation
template<typename _Tp, typename _Sequence = deque<_Tp>> std::queue< _Tp, _Sequence >::queue (const _Sequence
&__c) [inline], [explicit]
Default constructor creates no elements.
Definition at line 134 of file stl_queue.h.
Member Function Documentation
template<typename _Tp, typename _Sequence = deque<_Tp>> reference std::queue< _Tp, _Sequence >::back ()
[inline]
Returns a read/write reference to the data at the last element of the queue.
Definition at line 191 of file stl_queue.h.
template<typename _Tp, typename _Sequence = deque<_Tp>> const_reference std::queue< _Tp, _Sequence >::back ()
const [inline]
Returns a read-only (constant) reference to the data at the last element of the queue.
Definition at line 202 of file stl_queue.h.
template<typename _Tp, typename _Sequence = deque<_Tp>> bool std::queue< _Tp, _Sequence >::empty () const
[inline]
Returns true if the queue is empty.
Definition at line 156 of file stl_queue.h.
template<typename _Tp, typename _Sequence = deque<_Tp>> reference std::queue< _Tp, _Sequence >::front ()
[inline]
Returns a read/write reference to the data at the first element of the queue.
Definition at line 169 of file stl_queue.h.
template<typename _Tp, typename _Sequence = deque<_Tp>> const_reference std::queue< _Tp, _Sequence >::front
() const [inline]
Returns a read-only (constant) reference to the data at the first element of the queue.
Definition at line 180 of file stl_queue.h.
template<typename _Tp, typename _Sequence = deque<_Tp>> void std::queue< _Tp, _Sequence >::pop () [inline]
Removes first element. This is a typical queue operation. It shrinks the queue by one. The time
complexity of the operation depends on the underlying sequence.
Note that no data is returned, and if the first element's data is needed, it should be retrieved before
pop() is called.
Definition at line 244 of file stl_queue.h.
template<typename _Tp, typename _Sequence = deque<_Tp>> void std::queue< _Tp, _Sequence >::push (const
value_type &__x) [inline]
Add data to the end of the queue.
Parameters:
x Data to be added.
This is a typical queue operation. The function creates an element at the end of the queue and assigns
the given data to it. The time complexity of the operation depends on the underlying sequence.
Definition at line 218 of file stl_queue.h.
template<typename _Tp, typename _Sequence = deque<_Tp>> size_type std::queue< _Tp, _Sequence >::size () const
[inline]
Returns the number of elements in the queue.
Definition at line 161 of file stl_queue.h.
