SpeedoTransaction

public interface Transaction

extends javax.jdo.Transaction, org.objectweb.perseus.persistence.api.TransactionalWorkingSet

This interfaces defines the transaction concept in Speedo. It is based on a working set represented by the inheritance of the TransactionalWorkingSet interface, and the required javax.jdo.Transaction interface.

Method Detail

active

public void active()
            throws org.objectweb.perseus.persistence.api.PersistenceException

It activates the working set. This is used to delimit the begining of the working set.

Throws:

org.objectweb.perseus.persistence.api.PersistenceException

isManagedEnv

public boolean isManagedEnv()

Indicates if the transaction environnement is managed. If the 'false' value is returned then that means that a user transaction matches to a local transaction managed by speedo.

rollBackOnInternalError

public javax.jdo.JDOFatalException rollBackOnInternalError(java.lang.Exception e)

setConnectionHolder

public void setConnectionHolder(org.objectweb.perseus.persistence.api.ConnectionHolder ch)

Assignes the connection holder. The connection holder is able to allocate a connection to the underlying data support and to kept it until the working set / transaction end.
