Synopsis // 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 .
Public constructors RWSlistCollectablesQueue();
Construct an empty queue.
RWSlistCollectablesQueue(RWCollectable* a);
Construct an queue with single item a .
