Does anyone know how the operation below is performed? Which object has the hashtable built on it and which object performs the lookup against the hashtable once it's built?

| Operation                                      |  Name              |
-----------------------------------------------------------------------
|   0    SELECT STATEMENT                        |                    |
|   1  0 HASH JOIN                               |                    |
|   2  1  TABLE ACCESS FULL                      |B_TAB               |
|   3  1  INDEX FAST FULL SCAN                   |PK_A_TAB            |
