Detailed Description

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.

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 if autoDelete() is TRUE. Returns TRUE if there was an item to pop.

type* QStack::top () const

Returns a reference to the top item on the stack (most recently pushed). The stack is not changed.
