				Description: 
			
			
				 I provide an extension of ObjectPtr's services to
 include named accessors and utilities for
 SmallIntegers.
 
			
			   
			
				Public Methods: 
			
			
				
					  
					
					static ObjectPtr  
					
						create 
					
					(const SInteger aValue); 
					

					  I am create. I act as a "factory method" for creating new SmallInt
 objects.
 
					

					

					   
					

					static IntegerPtr  
					
						convert 
					
					(const ObjectPtr & obj); 
					

					  I convert obj to a valid IntegerPtr or gNil if obj wasn't an integer.
 
					

					

					   
					

					 
					
						IntegerPtr 
					
					(const ObjectPtr & pointee); 
					

					  This is the constructor. It has a default value of gNil, so it can
 be used as the generic constructor as well. This constructor
 creates a Object pointer that points to the address
 passed in through .
 
					

					

					   
					

					SInteger  
					
						value 
					
					(); 
					

					  I am the SInteger get accessor.
 
					

					

					   
					

					UInteger  
					
						asUInteger 
					
					(); 
					

					  I am a converter to UIntegers.
 
					

					

					   
					

					void  
					
						value 
					
					(const SInteger aValue); 
					

					  I am the SInteger set accessor. In reality, because of Smalltalk's
 definition, I actually create a new SInteger object to point to...
 i.e. I call create & set myself to point to the result of create..
 I am the method used to test the validity of the methods in IntegerPtr.
