Member Function Documentation

QQueue::QQueue ()

Creates an empty queue.

QQueue::QQueue ( const QQueue<type> & queue )

Creates a queue from another.

Only the pointers are copied.

QQueue::~QQueue ()

Destroys the list. Items in the list are destroyed if autoDelete() is TRUE.

QQueue::operator type* () const

Returns a reference to the first item in the queue. The queue is not changed.

type* QQueue::current () const

Returns a reference to the first item in the queue. The queue is not changed.

type* QQueue::dequeue ()

Removes the front item from the queue. Last in, last out.

void QQueue::enqueue ( const type * d )

Adds an item to the queue. Last in, last out.

type* QQueue::head () const

Returns a reference to the first item in the queue. The queue is not changed.

bool QQueue::isEmpty () const

Returns TRUE if there are no items to be dequeued

QQueue<type>& QQueue::operator= ( const QQueue<type> & queue )

Assigns queue to this queue and returns a reference to this queue.

This queue is first cleared, then each item in queue is enqueued to this queue. Only the pointers are copied (shallow copy).

bool QQueue::remove ()

Removes the front item from the queue. Last in, last out. The item is deleted if autoDelete() is TRUE. Returns TRUE if there was an item to remove.
