Like all OsidLists, CostList provides a means for accessing Cost elements sequentially either one at a time or many at a time. Examples:

                     
                     
                     while (cl.hasNext()) {
                          Cost cost = cl.getNextCost();
                     }
                     
                                 
                     
                

                     
                     
                     while (cl.hasNext()) {
                          Cost[] costs = cl.getNextCosts(cl.available());
                     }
