Detailed Description

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

std::stack::stack ( const _Sequence &  __c) [inline, explicit]

Default constructor creates no elements.

Definition at line 133 of file stl_stack.h.


Member Function Documentation

bool std::stack::empty ( ) const [inline]

Returns true if the stack is empty.

Definition at line 145 of file stl_stack.h.

void std::stack::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 211 of file stl_stack.h.

void std::stack::push ( const value_type &  __x) [inline]

Add data to the top of the stack.

Parameters:
xData 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 185 of file stl_stack.h.

size_type std::stack::size ( ) const [inline]

Returns the number of elements in the stack.

Definition at line 150 of file stl_stack.h.

reference std::stack::top ( ) [inline]

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

Definition at line 158 of file stl_stack.h.

const_reference std::stack::top ( ) const [inline]

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

Definition at line 169 of file stl_stack.h.
