Detailed Description

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

A standard container giving FILO 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-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_front, 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

template<typename _Tp, typename _Sequence>
std::stack< _Tp, _Sequence >::stack const _Sequence &    __c = _Sequence() [inline, explicit]
 

Default constructor creates no elements.

Definition at line 138 of file stl_stack.h.


Member Function Documentation

template<typename _Tp, typename _Sequence>
bool std::stack< _Tp, _Sequence >::empty   const [inline]
 

Returns true if the %stack is empty.

Definition at line 145 of file stl_stack.h.

template<typename _Tp, typename _Sequence>
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 188 of file stl_stack.h.

template<typename _Tp, typename _Sequence>
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 175 of file stl_stack.h.

template<typename _Tp, typename _Sequence>
size_type std::stack< _Tp, _Sequence >::size   const [inline]
 

Returns the number of elements in the %stack.

Definition at line 149 of file stl_stack.h.

template<typename _Tp, typename _Sequence>
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.

Definition at line 163 of file stl_stack.h.

template<typename _Tp, typename _Sequence>
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 156 of file stl_stack.h.
