java.lang.Object org.springframework.orm.jdo.support.JdoDaoSupport
Convenient super class for JDO data access objects.
Requires a PersistenceManagerFactory to be set, providing a JdoTemplate based on it to subclasses. Can alternatively be initialized directly via a JdoTemplate, to reuse the latter's settings like PersistenceManagerFactory, JdoDialect, flush mode, etc.
This base class is mainly intended for JdoTemplate usage but can also
be used when working with PersistenceManagerFactoryUtils directly, e.g. in
combination with JdoInterceptor-managed PersistenceManagers. Convenience
getPersistenceManager
and closePersistenceManagerIfNecessary
methods are provided for that usage style.
This class will create its own JdoTemplate if only a PersistenceManagerFactory
is passed in. The allowCreate flag on that JdoTemplate will be true by default.
A custom JdoTemplate instance can be used through overriding createJdoTemplate
.

createJdoTemplate(javax.jdo.PersistenceManagerFactory persistenceManagerFactory)
Create a JdoTemplate for the given PersistenceManagerFactory. |

getJdoTemplate()
Return the JdoTemplate for this DAO, pre-initialized with the PersistenceManagerFactory or set explicitly. |
