Subject [jira] Created: (JDO-166) Implement new JDO 2 query tests cases concerning deletion by query.
Date Tue, 04 Oct 2005 12:45:47 GMT
Implement new JDO 2 query tests cases concerning deletion by query.

         Key: JDO-166
         URL: http://issues.apache.org/jira/browse/JDO-166
     Project: JDO
        Type: New Feature
  Components: tck20  
    Reporter: Michael Watzek
 Assigned to: Michael Watzek 

We need 4 new test classes, one for each of the following assertions:

- A14.8-1: These methods delete the instances of affected classes that pass the filter, and
all dependent instances. Affected classes are the candidate class and its persistence-capable
- A14.8-2: The number of instances of affected classes that were deleted is returned. Embedded
instances and dependent instances are not counted in the return value.
- A14.8-3: Query elements filter, parameters, imports, variables, and unique are valid in
queries used for delete. Elements result, result class, range, grouping, and ordering are
invalid. If any of these elements is set to its non-default value when one of the deletePersistentAll
methods is called, a JDOUserException is thrown and no instances are deleted.
- A14.8-4: Dirty instances of affected classes are first flushed to the datastore. Instances
already in the cache when deleted via these methods or brought into the cache as a result
of these methods undergo the life cycle transitions as if deletePersistent had been called
on them. That is, if an affected class implements the DeleteCallback interface, the instances
to be deleted are instantiated in memory and the jdoPreDelete method is called prior to deleting
the instance in the datastore. If any LifecycleListener instances are registered with affected
classes, these listeners are called for each deleted instance. Before returning control to
the application, instances of affected classes in the cache are refreshed by the implementation
so their status in the cache reflects whether they were deleted from the datastore.
