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

                     
                     
                     while (pl.hasNext()) {
                          Proficiency proficiency = pl.getNextProficiency();
                     }
                     
                                 
                     
                

                     
                     
                     while (pl.hasNext()) {
                          Proficiency[] proficiencies = pl.getNextProficiencies(pl.available());
                     }
