DESCRIPTION

CNQueueRandom is a queue, implemented as a doubly linked list, that can contain any number (well, sort of ... ;-) CNCL compatible objects. The queueing strategy is Random, that means there is no ordering in the queue.

Constructors:

CNQueueRandom();

CNQueueRandom(CNParam *param);

CNQueueRandom(CNRNG *rng);

Initialize the Random-queue to an empty state. One may provide a base random number generator (recommended!), otherwise the queue provides its own (default setting: CNFiboG.)

In addition to the member functions required by CNCL, CNQueueRandom 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 a random 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.
