					static ObjectPtr  
					
						create 
					
					( ); 
					

					  I am the factory method used to create a new gc stack object.
 
					

					

					   
					

					static StackPtr  
					
						convert 
					
					( ObjectPtr ); 
					

					  I am the tool used to verify an object can support
 my facilities.
 
					

					

					   
					

					 
					
						StackPtr 
					
					( const ObjectPtr & ); 
					

					  I am a constructor.  I simply construct a StackPtr from some
 ObjectPtr.
 
					

					

					   
					

					ObjectPtr &  
					
						top 
					
					(); 
					

					  Return the current top of stack without removing it.
 Gives us the ability to look before we leap without as
 much expense.
 
					

					

					   
					

					ObjectPtr  
					
						pop 
					
					( ); 
					

					  I am the accessor: I return the object on the top of my
 stack and then release it.
 
					

					

					   
					

					void  
					
						push 
					
					( const ObjectPtr & aValue ); 
					

					  I am the mutator: I create a new node that points to aValue.
 
					

					

					   
					

					static ClassPtr &  
					
						klassPtr 
					
					(); 
					

					  I am a accessor to the class that my objects should be.

 stack.
