running trough a binary_indexed table in PL/SQL

What is the best/fastest way of for-looping trough all entries in a binary_indexed table in PL/SQL?

I want to do something like:

declare
  type tab_type is table of number(10) index by binary_integer;   tab tab_type;
begin
...

  for keys tab loop
    ...
  end loop;
...
