org.apache.derby.iapi.store.raw.xact
Interface TransactionFactory
- All Superinterfaces:
- org.apache.derby.iapi.store.raw.Corruptable
- public interface TransactionFactory
- extends org.apache.derby.iapi.store.raw.Corruptable
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.
