How can use this TYPE

Question

Hi all,
I'm quite new to this, please see the code below.
CREATE OR REPLACE TYPE "test" AS OBJECT
"first" NUMBER(4),
CONSTRUCTOR FUNCTION "test"(param varchar2(200)) RETURN SELF AS RESULT
)NOT FINAL INSTANTIABLE;
create or replace type body "test" is
CONSTRUCTOR FUNCTION "test"(param varchar2(200)) RETURN SELF AS RESULT is
begin
select to_char(sysdate, 'YYYY')
into self."first"
from dual;
return;
end;
end;
how can i retrieve information from the type above in pl/sql?
Thanks in advance

Ok, so here we go:
michaels>  create or replace type pl_tabobj as object (
   rn    number,
   val   varchar2 (10)
Type created.
michaels>  create or replace type pl_tabtype as table of pl_tabobj
Type created.
michaels>  create sequence pl_tabtype_seq
Sequence created.
michaels>  create or replace function f_array (p_list in varchar2)
   return pl_tabtype pipelined
as
   v_str    varchar2 (1024) default p_list || ',';
   v_len    number;
   v_data   pl_tabtype := pl_tabtype(pl_tabobj(null,null));
begin
   loop
      v_len := instr (v_str, ',');
      exit when (nvl (v_len, 0) = 0);
      select pl_tabobj(pl_tabtype_seq.nextval,trim (substr (v_str, 1, v_len - 1)))
        into  v_data(v_data.count)
        from dual;
      v_str := substr (v_str, v_len + 1);
      pipe row (v_data(v_data.count));
   end loop;
   return;
end f_array;
Function created.
