30  * This is an aspect-oriented annotation and triggers certain behavior.
31  *
32  * It allows a field to have the value of itself pertain
33  * to the current transaction.
34  *
35  * The fields transactional and non-transactional value is always separate
36  * At tx commit, the transactional value the field had is wiped away.
37  * At tx commit, the transactional value does not correspond to the non-transactional value
38  *
39  * If you are within a transaction and you get the value of the field before setting it
40  * then the initial transational value will be set to the current non-transactional value
