public abstract class CciDaoSupport
extends DaoSupport

Convenient super class for CCI-based data access objects.

Requires a ConnectionFactory to be set, providing a CciTemplate based on it to subclasses through the getCciTemplate() method.

This base class is mainly intended for CciTemplate usage but can also be used when working with a Connection directly or when using org.springframework.jca.cci.object classes.

1.2

Constructor Detail

CciDaoSupport

public CciDaoSupport()
Method Detail

setConnectionFactory

public final void setConnectionFactory(javax.resource.cci.ConnectionFactory connectionFactory)
Set the ConnectionFactory to be used by this DAO.


createCciTemplate

protected CciTemplate createCciTemplate(javax.resource.cci.ConnectionFactory connectionFactory)
Create a CciTemplate for the given ConnectionFactory. Only invoked if populating the DAO with a ConnectionFactory reference!

Can be overridden in subclasses to provide a CciTemplate instance with different configuration, or a custom CciTemplate subclass.

Parameters:
connectionFactory - the CCI ConnectionFactory to create a CciTemplate for
Returns:
the new CciTemplate instance
See Also:
setConnectionFactory(javax.resource.cci.ConnectionFactory)

getConnectionFactory

public final javax.resource.cci.ConnectionFactory getConnectionFactory()
Return the ConnectionFactory used by this DAO.


setCciTemplate

public final void setCciTemplate(CciTemplate cciTemplate)
Set the CciTemplate for this DAO explicitly, as an alternative to specifying a ConnectionFactory.


getCciTemplate

public final CciTemplate getCciTemplate()
Return the CciTemplate for this DAO, pre-initialized with the ConnectionFactory or set explicitly.


checkDaoConfig

protected final void checkDaoConfig()
Description copied from class: DaoSupport
Abstract subclasses must override this to check their configuration.

Implementors should be marked as final

Specified by:
checkDaoConfig in class DaoSupport

getCciTemplate

protected final CciTemplate getCciTemplate(javax.resource.cci.ConnectionSpec connectionSpec)
Obtain a CciTemplate derived from the main template instance, inheriting the ConnectionFactory and other settings but overriding the ConnectionSpec used for obtaining Connections.

Parameters:
connectionSpec - the CCI ConnectionSpec that the returned template instance is supposed to obtain Connections for
Returns:
the derived template instance
See Also:
CciTemplate.getDerivedTemplate(javax.resource.cci.ConnectionSpec)

getConnection

protected final javax.resource.cci.Connection getConnection()
                                                     throws CannotGetCciConnectionException
Get a CCI Connection, either from the current transaction or a new one.

Returns:
the CCI Connection
Throws:
CannotGetCciConnectionException - if the attempt to get a Connection failed
See Also:
ConnectionFactoryUtils.getConnection(javax.resource.cci.ConnectionFactory)

releaseConnection

protected final void releaseConnection(javax.resource.cci.Connection con)
Close the given CCI Connection, created via this bean's ConnectionFactory, if it isn't bound to the thread.

Parameters:
con - Connection to close
See Also:
ConnectionFactoryUtils.releaseConnection(javax.resource.cci.Connection, javax.resource.cci.ConnectionFactory)
