DESCRIPTION
The QStack class is a template class that provides a stack.

QStack is implemented as a template class. Define a template instance QStack<X> to create a stack that operates on pointers to X, or X*.

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().

MEMBER FUNCTION DOCUMENTATION

QStack::QStack ()
Creates and empty stack.

QStack::QStack ( const QStack<type> & s )
Creates a stack by making a shallow copy of another stack.

QStack::~QStack ()
Destroys the stack. All items will be deleted if autoDelete() is TRUE.

QStack::operator type* () const
Returns a reference to the top item on the stack (most recently pushed). The stack is not changed.

bool QStack::autoDelete () const
The same as QCollection::autoDelete().

See also setAutoDelete().

void QStack::clear () [virtual]
Removes all items from the stack, deleting them if autoDelete() is TRUE.

See also remove().

Reimplemented from QCollection.

uint QStack::count () const [virtual]
Returns the number of items in the stack.

See also isEmpty().

Reimplemented from QCollection.

type* QStack::current () const
Returns a reference to the top item on the stack (most recently pushed). The stack is not changed.

bool QStack::isEmpty () const
Returns TRUE is the stack contains no elements to be popped

QStack<type>& QStack::operator= ( const QStack<type> & s )
Sets the contents of this stack by making a shallow copy of another stack. Elements currently in this stack will be deleted if autoDelete() is TRUE.

type* QStack::pop ()
Removes the top item from the stack and returns it.

void QStack::push ( const type * d )
Adds an element to the top of the stack. Last in, first out.

bool QStack::remove ()
Removes the top item from the stack and deletes it if autoDelete() is TRUE. Returns TRUE if there was an item to pop.

See also clear().

void QStack::setAutoDelete ( bool enable )
The same as QCollection::setAutoDelete().

See also autoDelete().

type* QStack::top () const
Returns a reference to the top item on the stack (most recently pushed). The stack is not changed.
