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.AbstractThreadedTransaction
