## org.springframework.jca.cci.core.support
Class CciDaoSupport

    java.lang.Object
      org.springframework.dao.support.DaoSupport
          org.springframework.jca.cci.core.support.CciDaoSupport

All Implemented Interfaces:
  InitializingBean

    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.

Since:
  1.2
Author:
  Thierry Templier, Juergen Hoeller

  `setConnectionFactory(javax.resource.cci.ConnectionFactory)`, `getCciTemplate()`, `CciTemplate`

Method Summary
`protected void` | `checkDaoConfig()` Abstract subclasses must override this to check their configuration.
`protected CciTemplate` | `createCciTemplate(ConnectionFactory connectionFactory)` Create a CciTemplate for the given ConnectionFactory.
`CciTemplate` | `getCciTemplate()` Return the CciTemplate for this DAO, pre-initialized with the ConnectionFactory or set explicitly.
`protected CciTemplate` | `getCciTemplate(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.
`protected Connection` | `getConnection()` Get a CCI Connection, either from the current transaction or a new one.
`ConnectionFactory` | `getConnectionFactory()` Return the ConnectionFactory used by this DAO.
`protected void` | `releaseConnection(Connection con)` Close the given CCI Connection, created via this bean's ConnectionFactory, if it isn't bound to the thread.
`void` | `setCciTemplate(CciTemplate cciTemplate)` Set the CciTemplate for this DAO explicitly, as an alternative to specifying a ConnectionFactory.
`void` | `setConnectionFactory(ConnectionFactory connectionFactory)` Set the ConnectionFactory to be used by this DAO.

Constructor Detail

### CciDaoSupport

    public CciDaoSupport()

Method Detail

### setConnectionFactory

    public final void setConnectionFactory(ConnectionFactory connectionFactory)

  Set the ConnectionFactory to be used by this DAO.

### createCciTemplate

    protected CciTemplate createCciTemplate(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 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(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 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(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)`
