| Method | getNextGraphNode | ||
| Description | 
                     Gets the next   | ||
| Return | osid.topology.GraphNode | the next  GraphNode  in this list. The  hasNext() 
 method should be used to test that a next  GraphNode  is 
available before calling this method.  | |
| Errors | ILLEGAL_STATE | no more elements available in this list | |
| OPERATION_FAILED | unable to complete request | ||
| Compliance | mandatory | This method must be implemented. | |
| Method | getNextGraphNodes | ||
| Description | 
                     Gets the next set of   | ||
| Parameters | cardinal | n | the number of  GraphNode  elements requested which must be 
less than or equal to  available()   | 
| Return | osid.topology.GraphNode[] | an array of  GraphNode  elements.   The length of 
the array is less than or equal to the number specified.  | |
| Errors | ILLEGAL_STATE | no more elements available in this list | |
