O PL/SQL tem um StringTokenizer equivalente ao do Java?

DECLARE
   lv_tab_length   BINARY_INTEGER;
   lt_array   DBMS_UTILITY.lname_array;
BEGIN
   DBMS_UTILITY.COMMA_TO_TABLE( list => 'one,two,three,four'
                              , tablen => lv_tab_length
                              , tab => lt_array
                              );

   DBMS_OUTPUT.PUT_LINE( 'lv_tab_length = ['||lv_tab_length||']' );

   FOR i IN 1..lv_tab_length
   LOOP
      DBMS_OUTPUT.PUT_LINE( '['||lt_array( i )||']' );
   END LOOP;

END;
