All known Subclasses: org.apache.derby.impl.store.raw.xact.XactFactory,
| TransactionFactory | | public interface TransactionFactory extends Corruptable(Code) | | This module is intended to be used only within the RawStore. RawStore functionality
is accessed only through the RawStoreFactory interface.
The transaction manager is responsible for:
- Generating unique transaction identifiers.
- Keeping a list of all open transactions within the raw store.
See Also: RawStoreFactory

exception:
StandardException - if interrupted or a runtime exception occurs. |
| findTransaction | | public boolean findTransaction(TransactionId id, RawTransaction tran)(Code) | | Find a transaction using a transactionId and make the passed in
transaction assume the identity and properties of that transaction.
Used in recovery only.

and restore their state such that they remain after recovery, and
can be found and handled by a XA transaction manager. This includes
creating a context manager for each, pushing a xact context, and
reclaiming update locks on all data changed by the transaction.
Used only in recovery.
exception:
StandardException - Cloudscape Standard Error policy |
