Package de.xima.fc.persistence.impl.tx

Class JpaTransaction

java.lang.Object

de.xima.fc.persistence.impl.tx.JpaTransaction

All Implemented Interfaces:

IJpaTransaction, Closeable, AutoCloseable

public class JpaTransaction
extends Object
implements IJpaTransaction

Implementation of IJpaTransaction that manages a JPA transaction using an EntityManager. This class ensures that the transaction is properly started, committed, or rolled back as needed.

Such a transaction stands alone: nothing takes part in it, and work done in it is committed or rolled back on its own. A transaction other work can take part in is opened by the JpaTransactionRunner.

Note: This class is designed for internal use only. Plugins should not use this interface. This class may be moved to a different package in the future, so plugins should not depend on it.

Since:

8.5.0
