Does exists a "pseudo column" in collection type?

Does exists a "pseudo column" in collection type that identify a record univocally? 

Example code: 

I wrote ROWID as example of univocal id

CREATE OR REPLACE TYPE ADDRESS_TYP AS OBJECT

(

   STREET VARCHAR2 (30),

   CITY VARCHAR2 (20),

   STATE CHAR (2),

   POSTAL_CODE VARCHAR2 (6)

);

/

CREATE OR REPLACE TYPE ADDRESS_TYP_TABLE AS TABLE OF ADDRESS_TYP;

/

DECLARE

   TAB_ADDRESS   ADDRESS_TYP_TABLE;

BEGIN

   TAB_ADDRESS :=

      ADDRESS_TYP_TABLE (ADDRESS_TYP ('kong gate',

                                      'oslo',

                                      'no',

                                      '0135'),

                         ADDRESS_TYP ('dronning gate',

                                      'oslo',

                                      'no',

                                      '0136'));

   FOR R IN (SELECT STREET

             --, ROWID 

             FROM TABLE (TAB_ADDRESS))

   LOOP

      DBMS_OUTPUT.PUT_LINE ('street: ' || R.STREET
