QValueStack is part of the \link + qtl.html Qt Template Library\endlink. + + Note that QValueStack does not store pointers to the members of + the stack; it holds a copy of every member. That is why these + kinds of classes are called "value based"; QPtrStack, QPtrList, + QDict, etc., are "pointer based". + + A stack is a last in, first out (LIFO) structure. Items are added + to the top of the stack with push() and retrieved from the top + with pop(). The top() function provides access to the topmost item + without removing it. + + Example: + \code + QValueStack stack; + stack.push( 1 ); + stack.push( 2 ); + stack.push( 3 ); + while ( ! stack.isEmpty() ) + cout << "Item: " << stack.pop() << endl; + + // Output: + // Item: 3 + // Item: 2 + // Item: 1 + \endcode + + QValueStack is a specialized QValueList provided for convenience. + All of QValueList's functionality also applies to QPtrStack, for + example the facility to iterate over all elements using + QValueStack::Iterator. See QValueListIterator for further + details. + + Some classes cannot be used within a QValueStack, for example + everything derived from QObject and thus all classes that + implement widgets. Only values can be used in a QValueStack. To + qualify as a value, the class must provide + \list + \i a copy constructor; + \i an assignment operator; + \i a default constructor, i.e. a constructor that does not take any arguments. + \endlist + + Note that C++ defaults to field-by-field assignment operators and + copy constructors if no explicit version is supplied. In many + cases this is sufficient. +*/ + + +/*! + \fn QValueStack::QValueStack() + + Constructs an empty stack. +*/ + +/*! + \fn QValueStack::~QValueStack() + + Destroys the stack. References to the values in the stack and all + iterators of this stack become invalidated. Because QValueStack is + highly tuned for performance, you won't see warnings if you use + invalid iterators because it is impossible for an iterator to + check whether or not it is valid. +*/ + + +/*! + \fn void QValueStack::push( const T& d ) + + Adds element, \a d, to the top of the stack.
