Synopsis // Smalltalk typedef:
typedef RWSlistCollectablesStackStack;
#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 .
Public constructors RWSlistCollectablesStack();
Construct an empty stack.
RWSlistCollectablesStack(RWCollectable* a);
Construct a stack with one entry a .
RWSlistCollectablesStack(const RWSlistCollectablesStack&
s);
Copy constructor. A shallow copy of the stack s is made.
