Deleting/Updating records from an object table in PL/SQL

Question

Hello All,
VER:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
PL/SQL Release 11.2.0.3.0 - Production
CORE     11.2.0.3.0     Production
TNS for Linux: Version 11.2.0.3.0 - Production
NLSRTL Version 11.2.0.3.0 - Production
I have created an object and inserted records in it. Is there any way we can delete/update records from it. I do not want to delete based on iteration like delete.collection but I would like to know if we can delete directly from obj like delete from table...
CREATE OR REPLACE TYPE test_type AS OBJECT
col1 number,
col2 varchar2(100)
CREATE OR REPLACE TYPE tab_type is table of test_type;
DECLARE
test_tab tab_type;
l_cnt NUMBER;
BEGIN
select test_type(col1,col2) bulk collect
into test_tab from (select 1 as col1,'test1' as col2 from dual
                    union all
                    select 2,'test2' from dual);
IF test_tab.count>0
THEN
DELETE FROM TABLE(CAST(test_tab as tab_type)) a
where a.col1=1;
END IF;
l_cnt := test_tab.count;
END;Thx
Shank.

SB,
I have a scenario wherein I insert few records into a collection table. I'm gonna filter few records from collection table based on the filter.
I want to delete the records that didn't match the filter. Right now, I'm inserting the records into a physical table and deleting from there. I do no want to use a physical table. Trying to avoid it.
Would like to delete from collection itself.
DELETE FROM TABLE(CAST(lv_attr_filter_tab as EDMS_CSPP_DISC_REQ_TAB_TYPE))
                             WHERE NOT EXISTS (SELECT 1
                                   FROM edms_disc_lines_stg edls
                                   WHERE edls.req_id = edrg.request_id
                                      AND edls.disc_line_id = edrg.discount_id
                                      AND UPPER(edls.disc_status) IN ('ACTIVE');
