Detailed Description

template<typename _Tp, typename _Sequence = deque<_Tp>>
class std::queue< _Tp, _Sequence >

A standard container giving FIFO behavior.

Template Parameters

_Tp	Type of element.
_Sequence	Type of underlying sequence, defaults to deque<_Tp>.

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.

Member Function Documentation

◆ back() [1/2]

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 238 of file stl_queue.h.

References std::queue< _Tp, _Sequence >::c.

◆ back() [2/2]

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 249 of file stl_queue.h.

References std::queue< _Tp, _Sequence >::c.

◆ emplace()

template<typename _Tp , typename _Sequence = deque<_Tp>>

inline

Definition at line 276 of file stl_queue.h.

◆ empty()

template<typename _Tp , typename _Sequence = deque<_Tp>>

bool std::queue< _Tp, _Sequence >::empty ( ) const

inline

Returns true if the queue is empty.

References std::queue< _Tp, _Sequence >::c.

◆ front() [1/2]

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 216 of file stl_queue.h.

References std::queue< _Tp, _Sequence >::c.

◆ front() [2/2]

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 227 of file stl_queue.h.

References std::queue< _Tp, _Sequence >::c.

◆ pop()

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 298 of file stl_queue.h.

References std::queue< _Tp, _Sequence >::c.

◆ push() [1/2]

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.

References std::queue< _Tp, _Sequence >::c.

◆ push() [2/2]

template<typename _Tp , typename _Sequence = deque<_Tp>>

◆ size()

template<typename _Tp , typename _Sequence = deque<_Tp>>

size_type std::queue< _Tp, _Sequence >::size ( ) const

inline

Returns the number of elements in the queue.
