							|  |  |  | The \module{copy_reg} module provides support for the | 
					
						
							| 
									
										
										
										
											1999-04-22 21:23:22 +00:00
										 |  |  | \refmodule{pickle}\refstmodindex{pickle} and | 
					
						
							|  |  |  | \refmodule{cPickle}\refbimodindex{cPickle} modules.  The | 
					
						
							|  |  |  | \refmodule{copy}\refstmodindex{copy} module is likely to use this in the | 
					
						
							|

										 |  |  | future as well.  It provides configuration information about object | 
					
						
							|  |  |  | constructors which are not classes.  Such constructors may be factory | 
					
						
							|  |  |  | functions or class instances. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | \begin{funcdesc}{constructor}{object} | 
					
						
							|  |  |  |   Declares \var{object} to be a valid constructor. | 
					
						
							|  |  |  | \end{funcdesc} | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | \begin{funcdesc}{pickle}{type, function\optional{, constructor}} | 
					
						
							|  |  |  |   Declares that \var{function} should be used as a ``reduction'' | 
					
						
							|  |  |  |   function for objects of type or class \var{type}.  \var{function} | 
					
						
							|  |  |  |   should return either a string or a tuple.  The optional | 
					
						
							|  |  |  |   \var{constructor} parameter, if provided, is a callable object which | 
					
						
							|  |  |  |   can be used to reconstruct the object when called with the tuple of | 
					
						
							|  |  |  |   arguments returned by \var{function} at pickling time. |
