Interface JdoOperations

All Known Implementing Classes:

JdoTemplate

Deprecated.

as of Spring 3.1, in favor of native PersistenceManager usage (see TransactionAwarePersistenceManagerFactoryProxy and SpringPersistenceManagerProxyBean)

@Deprecated
public interface JdoOperations

Interface that specifies a basic set of JDO operations, implemented by JdoTemplate. Not often used, but a useful option to enhance testability, as it can easily be mocked or stubbed.

Defines JdoTemplate's data access methods that mirror various JDO PersistenceManager methods. Users are strongly encouraged to read the JDO PersistenceManager javadocs for details on the semantics of those methods.

Note that lazy loading will just work with an open JDO PersistenceManager, either within a managed transaction or within OpenPersistenceManagerInViewFilter/ OpenPersistenceManagerInViewInterceptor. Furthermore, some operations just make sense within transactions, for example: evict, evictAll, flush.

Updated to build on JDO 2.0 or higher, as of Spring 2.5.

Since:

1.1

Method Detail

execute

<T> T execute(JdoCallback<T> action)
          throws DataAccessException

Deprecated.

Execute the action specified by the given action object within a PersistenceManager. Application exceptions thrown by the action object get propagated to the caller (can only be unchecked). JDO exceptions are transformed into appropriate DAO ones. Allows for returning a result object, i.e. a domain object or a collection of domain objects.

Note: Callback code is not supposed to handle transactions itself! Use an appropriate transaction manager like JdoTransactionManager.

Parameters:

action - callback object that specifies the JDO action

Returns:

a result object returned by the action, or null

Throws:

DataAccessException - in case of JDO errors

See Also:

JdoTransactionManager, PersistenceManager

executeFind

Collection executeFind(JdoCallback<?> action)
                       throws DataAccessException

Deprecated.

Execute the specified action assuming that the result object is a Collection. This is a convenience method for executing JDO queries within an action.

Parameters:

action - callback object that specifies the JDO action

Returns:

a Collection result returned by the action, or null

Throws:

DataAccessException - in case of JDO errors

getObjectById

Object getObjectById(Object objectId)
                     throws DataAccessException

Deprecated.

Return the persistent instance with the given JDO object id, throwing an exception if not found.

A JDO object id identifies both the persistent class and the id within the namespace of that class.

Parameters:

objectId - a JDO object id of the persistent instance

Returns:

the persistent instance

Throws:

ObjectRetrievalFailureException - if not found

DataAccessException - in case of JDO errors

See Also:

PersistenceManager.getObjectById(Object, boolean)

getObjectById

<T> T getObjectById(Class<T> entityClass,
                  Object idValue)
                throws DataAccessException

Deprecated.

Return the persistent instance of the given entity class with the given id value, throwing an exception if not found.

The given id value is typically just unique within the namespace of the persistent class. Its toString value must correspond to the toString value of the corresponding JDO object id.

Usually, the passed-in value will have originated from the primary key field of a persistent object that uses JDO's application identity.

Parameters:

entityClass - a persistent class

idValue - an id value of the persistent instance

Returns:

the persistent instance

Throws:

ObjectRetrievalFailureException - if not found

DataAccessException - in case of JDO errors

See Also:

PersistenceManager.getObjectById(Object, boolean), PersistenceManager.getObjectById(Class, Object)
