NestedTransactionManager
class NestedTransactionManager implements TransactionManager (View source)
TransactionManager decorator that adds virtual nesting support.
Because this is managed in PHP and not the database, it has the following limitations:
- Committing a nested transaction won't change anything until the parent transaction is committed
- Rolling back a nested transaction means that the parent transaction must be rolled backed
DBAL describes this behaviour nicely in their docs: https://www.doctrine-project.org/projects/doctrine-dbal/en/2.8/reference/transactions.html#transaction-nesting
Properties
| protected | int | $transactionNesting | ||
| protected | TransactionManager | $child | ||
| protected | bool | $mustRollback | Set to true if all transactions must roll back to the parent |
