TransactionalSystem (Apache Jena - DBOE Transactions 4.1.0)

All Superinterfaces:

Transactional, Transactional

All Known Implementing Classes:

TransactionalBase
```
public interface TransactionalSystem
extends Transactional
```
Implementation side of a Transactional. Transactional presents the application facing view whereas this has all the possible steps of an implementation. Normally, the implementation of commit() is split up.

- Method Detail
  - commit
```
default void commit()
```
    Specified by:
    
    commit in interface Transactional
  - commitPrepare
```
void commitPrepare()
```
    Do the 2-phase "prepare" step after which the transaction coordinator decides whether to commit or abort. A TransactionalSystem must be prepared for both possibilities.
  - commitExec
```
void commitExec()
```
    Do the 2-phase "commit" step
  - detach
```
TransactionCoordinatorState detach()
```
    Suspend this transaction, detaching from the current thread. A new transaction on this thread can performed but the detached transaction still exists and if it is a write transaction it can still block other write transactions.
  - attach
```
void attach(TransactionCoordinatorState coordinatorState)
```
    Attach a transaction to this thread. A transaction system implementation usually imposes a rule that only one thread can have a transaction attached at a time.
  - getTxnMgr
```
TransactionCoordinator getTxnMgr()
```
    Get the associated TransactionCoordinator
  - getTransactionInfo
```
TransactionInfo getTransactionInfo()
```
    Return an information view of the transaction for this thread, if any. Returns null when there is no active transaction for this tread.
  - getThreadTransaction
```
Transaction getThreadTransaction()
```
    Return the transaction object for this thread. Low-level use only. To get information about the current transaction, call getTransactionInfo().
