Pipe Function And Materialized View

Pipe Function and Materialized View.

There is a materialized view:

CODECREATE MATERIALIZED VIEW MY_MAT_VIEW NOLOGGING
REFRESH FORCE
START WITH SYSDATE NEXT SYSDATE + 5/24/60
AS
SELECT F1,
F2,
F3
from SOMETAB;

And there is a pipelined function:

CODEDROP TYPE MY_MAT_VIEW_table_type;
DROP TYPE MY_MAT_VIEW_row_type;

CREATE TYPE MY_MAT_VIEW_row_type AS OBJECT
(
F1 number,
F2 varchar2(100),
F3 date
[code].......

I've noticed that when materialized view is near to be refreshed (every 5 minutes) there is some "delay" in getting result sets using this query:

SELECT *
FROM TABLE(FN_GET_MY_MAT_VIEW(100)) a;

And when the refresh is finished the result set returns immediately.

Question.

Is there a way to avoid such "delay" while materialized view is refreshing?
