Method Detail

onStateChanged

void onStateChanged(@Nullable
                  TransactionState prevState,
                  TransactionState newState,
                  Transaction tx)

State change callback for transaction. Note that unless transaction has been completed, it is possible to mark it for rollbackOnly by calling Transaction.setRollbackOnly() on the passed in transaction. You can check the return value of setRollbackOnly() method to see if transaction was indeed marked for rollback or not.

Parameters:

prevState - Previous state of the transaction. If transaction has just been started, then previous state is null.

newState - New state of the transaction. In majority of the cases this will be the same as tx.state(), but it is also possible that transaction may be marked for rollback concurrently with this method invocation, and in that case newState reflects the actual state of the transition this callback is associated with.

tx - Transaction whose state has changed.
