// Smalltalk typedef:
typedef RWSlistCollectablesQueue Queue ;
#include <rw/queuecol.h>
RWSlistCollectablesQueue a;
Description
Class RWSlistCollectablesQueue represents a restricted interface to class RWSlistCollectables to implement a first in first out
(FIFO) queue. A queue is a sequential list for which all insertions are made at one end (the "tail"), but all removals are made at
the other end (the "head"). Hence, the ordering is determined externally by the ordering of the insertions. Duplicates are
allowed.
An object stored by RWSlistCollectablesQueue must inherit abstract base class RWCollectable. The virtual function isEqual()
(see class RWCollectable) is required, to find a match between a target and an item in the queue.
This class corresponds to the Smalltalk class Queue.
