Detailed Description

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

A standard container giving FILO 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-last-out stack 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 back, push_back, and pop_back, such as std::list, std::vector, 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, pop, and top, which are standard stack/FILO operations.

Constructor & Destructor Documentation

stack()

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

template<typename _Seq = _Sequence, typename _Requires = typename enable_if<is_default_constructible<_Seq>::value>::type>

std::stack< _Tp, _Sequence >::stack ( )

inline

Default constructor creates no elements.

Definition at line 156 of file stl_stack.h.

Member Function Documentation

empty()

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

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

inline

Returns true if the stack is empty.

Definition at line 193 of file stl_stack.h.

pop()

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

void std::stack< _Tp, _Sequence >::pop ( )

inline

Removes first element.

This is a typical stack operation. It shrinks the stack 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 266 of file stl_stack.h.

push()

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

void std::stack< _Tp, _Sequence >::push ( const value_type &  __x )

inline

Add data to the top of the stack.

Parameters

__x	Data to be added.

This is a typical stack operation. The function creates an element at the top of the stack and assigns the given data to it. The time complexity of the operation depends on the underlying sequence.

Definition at line 233 of file stl_stack.h.

size()

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

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

inline

Returns the number of elements in the stack.

Definition at line 198 of file stl_stack.h.

top() [1/2]

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

reference std::stack< _Tp, _Sequence >::top ( )

inline

Returns a read/write reference to the data at the first element of the stack.

Definition at line 206 of file stl_stack.h.

top() [2/2]

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

const_reference std::stack< _Tp, _Sequence >::top ( ) const

inline

Returns a read-only (constant) reference to the data at the first element of the stack.
