All Implemented Interfaces:

Synchronization, Transaction

public class JTAJCATransactionImpl
extends TransactionImpl
implements Synchronization

A transaction that is synchronised with a Java Transaction Service (JTA) transaction with JCA. It is only used when using the JDO API within a JavaEE environment using the JCA adapter (i.e not for JPA).

Method Summary

Modifier and Type	Method and Description
void	afterCompletion(int status) Called by the transaction manager after the transaction is committed or rolled back.
void	beforeCompletion() Called by the transaction manager prior to the start of the two-phase transaction commit process.
boolean	getIsActive() Similar to "isActive" except that it just returns the "active" flag whereas the isActive() method can also embody rejoining to underlying transactions.
boolean	isActive() Accessor for whether the transaction is active.

Method Detail

getIsActive

public boolean getIsActive()

Description copied from class: TransactionImpl

Similar to "isActive" except that it just returns the "active" flag whereas the isActive() method can also embody rejoining to underlying transactions.

Specified by:

getIsActive in interface Transaction

Overrides:

getIsActive in class TransactionImpl

Returns:

The "active" flag

isActive

public boolean isActive()

Accessor for whether the transaction is active.

Specified by:

isActive in interface Transaction

Overrides:

isActive in class TransactionImpl

Returns:

Whether the transaction is active.

beforeCompletion

public void beforeCompletion()

Called by the transaction manager prior to the start of the two-phase transaction commit process.

Specified by:

beforeCompletion in interface Synchronization

afterCompletion

public void afterCompletion(int status)

Called by the transaction manager after the transaction is committed or rolled back. Must be synchronised because some callers expect to be owner of this object's monitor (internalPostCommit() calls closeSQLConnection() which calls notifyAll()).

Specified by:

afterCompletion in interface Synchronization

Parameters:

status - The status
