\class QPtrStack ntqptrstack.h
\brief The QPtrStack class is a template class that provides a stack.
\ingroup tools
QValueStack is an STL-compatible alternative to this class.
Define a template instance QPtrStack\<X\> to create a stack that
operates on pointers to X, (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(). Use top() to get a reference to the top element
without changing the stack.
You can control the stack's deletion policy with setAutoDelete().
For compatibility with the QPtrCollection classes current() and
remove() are provided; they both operate on the top().
\sa QPtrList QPtrQueue
*/
/*!
\fn QPtrStack::QPtrStack ()
Creates an empty stack.
*/
/*!
\fn QPtrStack::QPtrStack (const QPtrStack<type>& s)
Creates a stack by making a shallow copy of another stack \a s.
*/
/*!
\fn QPtrStack::~QPtrStack ()
Destroys the stack. All items will be deleted if autoDelete() is
TRUE.
*/
/*!
\fn QPtrStack<type>& QPtrStack::operator= (const QPtrStack<type>& s)
Sets the contents of this stack by making a shallow copy of
another stack \a s. Elements currently in this stack will be
deleted if autoDelete() is TRUE.
*/
/*!
\fn bool QPtrStack::isEmpty () const
Returns TRUE if the stack contains no elements; otherwise returns
FALSE.
*/
/*!
\fn void QPtrStack::push (const type* d)
Adds an element \a d to the top of the stack. Last in, first out.
*/
/*!
\fn type* QPtrStack::pop ()
Removes the top item from the stack and returns it. The stack must
not be empty.
*/
/*!
\fn bool QPtrStack::remove ()
Removes the top item from the stack and deletes it if autoDelete()
is TRUE. Returns TRUE if there was an item to pop; otherwise
returns FALSE.
\sa clear()
*/
/*!
\fn void QPtrStack::clear()
Removes all items from the stack, deleting them if autoDelete() is
TRUE.
\sa remove()
*/
/*!
\fn uint QPtrStack::count() const
Returns the number of items in the stack.
\sa isEmpty()
*/
/*!
\fn type* QPtrStack::top () const
Returns a pointer to the top item on the stack (most recently
pushed). The stack is not changed. Returns 0 if the stack is
empty.
*/
/*!
\fn QPtrStack::operator type* ()const
Returns a pointer to the top item on the stack (most recently
pushed). The stack is not changed. Returns 0 if the stack is
empty.
*/
/*!
\fn type* QPtrStack::current () const
Returns a pointer to the top item on the stack (most recently
pushed). The stack is not changed. Returns 0 if the stack is
empty.
*/
/*!
\fn bool QPtrStack::autoDelete() const
The same as QPtrCollection::autoDelete().
\sa setAutoDelete()
*/
/*!
\fn void QPtrStack::setAutoDelete( bool enable )
Defines whether this stack auto-deletes its contents. The same as
QPtrCollection::setAutoDelete().
If \a enable is TRUE the stack auto-deletes its contents; if \a
enable is FALSE the stack does not delete its contents.
\sa autoDelete()
*/
/*!
\fn QDataStream& QPtrStack::read( QDataStream& s,
QPtrCollection::Item& item )
Reads a stack item, \a item, from the stream \a s and returns a
reference to the stream.
The default implementation sets \a item to 0.
\sa write()
*/
/*!
\fn QDataStream& QPtrStack::write( QDataStream& s,
QPtrCollection::Item item ) const
Writes a stack item, \a item, to the stream \a s and returns a
reference to the stream.
The default implementation does nothing.
\sa read()
