DESCRIPTION

CNQueueLIFO is a queue, implemented as a doubly linked list, that can contain any number (well, sort of ... ;-) CNCL compatible objects. The queueing strategy is LIFO (Last In, First Out).

Constructors:

CNQueueLIFO();

CNQueueLIFO(CNParam *param);

Initialize the LIFO-queue to an empty state.

In addition to the member functions required by CNCL, CNQueueLIFO provides:

virtual bool empty() const;

Returns TRUE, if the queue is empty.

virtual bool full() const;

Always returns FALSE.

virtual int length() const;

Returns the actual queue length.

virtual void put(CNObject *obj);

Puts an object into the queue.

virtual CNObject *get();

Retrieves an object from the queue.

virtual CNObject *peek();

Retrieves an object from the queue. Unlike get(), the object is not removed from the queue.

virtual void delete_all();

Deletes all objects in the queue.
