public abstract class AbstractThreadLocalTransaction extends AbstractTransaction
Transaction that provides core functionality for transaction listeners using
ThreadLocal. In this implementation, the listeners are bound to the current thread of execution (usually
the same as the transaction for most graph database implementations). Therefore, when AbstractTransaction.commit() is
called on a particular thread, the only listeners that get notified are those bound to that thread.AbstractThreadedTransactionAbstractTransaction.TransactionExceptionTransaction.CLOSE_BEHAVIOR, Transaction.Exceptions, Transaction.READ_WRITE_BEHAVIOR, Transaction.Status, Transaction.Workload<R>| Modifier and Type | Field and Description |
