RecreateSerializedObjects()

JOLTObject *RecreateSerializedObjects( poTree, poParent );

PTNSubTree *poTree;
               A parse tree containing the definition of a hierarchy of
               JOLTObjects.  It will be used to create the objects.

JOLTObject *poParent;
               A JOLTObject to to which the created object(s) should be
               attached as a child tree.  This may be NULL.

The RecreateSerializedObjects() method on the JOLTRegistry is used to create a set of objects from the contents of a parse tree. Normally the parse tree would be read from an ASCII file using the PTNSubTree::BuildFromFile() method. The PTNSubTree is not altered by RecreateSerializedObjects. All object classes to be recreated from the PTNSubTree must have been registered, with Create functions (see the RegisterClass() method) before calling RecreateSerializedObjects().

A trappable IMP error will be generated if object deserialization fails for some reason.

   FILE        *fp;
   PTNSubTreeNode *poPTNRoot = HNew PTNSubTree( "Root" );
   PCLIter     oIter;

   fp = DKOpen( pszFilename, FL_TXT, "r" );
   poPTNRoot->BuildFromFile( fp );
   DKClose( fp );

   for( oIter.Start(poPTNRoot->GetChildren());
        oIter.Current() != NULL;
        oIter.Next() )
   {
       JOLTObject      *poObject;

       poObject = GetJOLTRegistry()->RecreateSerializedObjects( poPTNRoot,
                                                                NULL );

       Debug( "<Recreated `%s'>\n", poObject->GetName() );
   }
