Is there any way to pass through PIPELINED function

Question

Hello,
For clarity of my code I would like to move some part of my PIPELINED function out to sub-function. It there any way to call one PIPELINED function from other PIPELINED function a way to union their results?
I can try to use temporary table to emulate such behavior, but it won't be exactly the same...
Regards

Yes, you can. The only thing you need to remember is pipelined function can be salled from SQL only. So your functions will look like:
Pipelined function 1:
create or replace
  function pipelined_function1(...)
    return ...
    pipelined
    is
    begin
        pipe row(...);
end;
/Pipelined function 2:
create or replace
  function pipelined_function2(...)
    return ...
    pipelined
    is
    begin
        for v_rec in (select * from table(pipelined_function1(...))) loop
          pipe row(...);
        end loop;
        pipe row(...);
end;
/SY.
