Detailed Description
template<typename_Tp,typename_Sequence=deque<_Tp>>
class std::stack< _Tp, _Sequence >"A standard container giving FILO behavior.
TemplateParameters_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.
Member Function Documentation
template<typename_Tp,typename_Sequence=deque<_Tp>>boolstd::stack<_Tp,_Sequence>::empty()const[inline]
Returns true if the stack is empty.
template<typename_Tp,typename_Sequence=deque<_Tp>>voidstd::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.
template<typename_Tp,typename_Sequence=deque<_Tp>>voidstd::stack<_Tp,_Sequence>::push(constvalue_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.
template<typename_Tp,typename_Sequence=deque<_Tp>>size_typestd::stack<_Tp,_Sequence>::size()const[inline]
Returns the number of elements in the stack.
template<typename_Tp,typename_Sequence=deque<_Tp>>referencestd::stack<_Tp,_Sequence>::top()[inline]
Returns a read/write reference to the data at the first element of the stack.
template<typename_Tp,typename_Sequence=deque<_Tp>>const_referencestd::stack<_Tp,_Sequence>::top()const[inline]
Returns a read-only (constant) reference to the data at the first element of the stack.
