/**
* Interface that specifies a basic set of JDO operations,
* implemented by {@link JdoTemplate}. Not often used, but a useful
* option to enhance testability, as it can easily be mocked or stubbed.
*
* Defines {@code JdoTemplate}'s data access methods that mirror
* various JDO {@link javax.jdo.PersistenceManager} methods. Users are
* strongly encouraged to read the JDO {@code PersistenceManager}
* javadocs for details on the semantics of those methods.
*
*
Note that lazy loading will just work with an open JDO
* {@code PersistenceManager}, either within a managed transaction or within
* {@link org.springframework.orm.jdo.support.OpenPersistenceManagerInViewFilter}/
* {@link org.springframework.orm.jdo.support.OpenPersistenceManagerInViewInterceptor}.
* Furthermore, some operations just make sense within transactions,
* for example: {@code evict}, {@code evictAll}, {@code flush}.
*
*
Updated to build on JDO 2.0 or higher, as of Spring 2.5.
