Synopsis
// Smalltalk typedef:
typedef RWSlistCollectablesStack Stack;
#include <rw/stackcol.h>
RWSlistCollectablesStack a;
Description
Class RWSlistCollectablesStack represents a restricted interface to class RWSlistCollectables to implement a last in first out
(LIFO) stack. A Stack is a sequential list for which all insertions and deletions are made at one end (the beginning of the list).
Hence, the ordering is determined externally by the ordering of the insertions. Duplicates are allowed.
An object stored by RWSlistCollectablesStack 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 stack.
This class corresponds to the Smalltalk class Stack.

RWSlistCollectablesStack(const RWSlistCollectablesStack& s);
Copy constructor. A shallow copy of the stack s is made.
