Collection question: access and reference

Question

Hello all:
i've created the following type:
CREATE OR REPLACE
type hh_entry as object(
qa_hh_id     NUMBER,
src_cd          VARCHAR2(4),
hrm_hh_id     VARCHAR2(50),
init_hh_id     VARCHAR2(50),
sip_hh_id     VARCHAR2(50),
client_id     VARCHAR2(50)
then created a collection for it
type hh_bucket is table of hh_entry index by binary_integer;
i instantiate the collection:
bucket1 hh_pkg.hh_bucket;
then I populate it in a loop, accessing by an index.
example:
loop
bucket1(index_val) := some new value;
end loop;
OK, so I've the collection populate with all kinds of data....
if I wanted to select all the bucket1.qa_hh_id 's
in bucket1, how could I do it?

Thanks for all the help so far... I think I have one more obstacle to overcome.
I have the following SQL objects/types:
CREATE OR REPLACE
type hh_entry as object(
qa_hh_id     NUMBER,
src_cd          VARCHAR2(4),
hrm_hh_id     VARCHAR2(50),
init_hh_id     VARCHAR2(50),
sip_hh_id     VARCHAR2(50),
client_id     VARCHAR2(50)
CREATE OR REPLACE
type hh_bucket is table of hh_entry
And I want to use them in my PL/SQL code. The problem I'm having is when I go to use the table
I create the table:
bucket1 hh_bucket;
then I initialize:
bucket1 := hh_bucket();
when I go to insert:
bucket1(index) := entry;
I get the following:
ORA-06533: Subscript beyond count
ORA-06512: at "HH_COMP", line 96
ORA-06512: at line 1
How can I initialize the table so that this error will not happen. I can make it work if I know how many entries i will be inserting, for 3 entries
bucket1 := hh_bucket(NULL, NULL, NULL);
works fine, but I don't know before hand how many entries there will be......
help?
