List of alterProjection() Examples

Examples of alterProjection()

org.rhq.enterprise.server.util.CriteriaQueryGenerator.alterProjection()

If you want to return something other than the list of entities represented by the passed Criteria object, you can alter the projection here to return a customized subset or superset of data. The projection will only affect the ResultSet for the data query, not the count query.

If you are projecting a composite object that does not directly extend the entity your Criteria object represents, then you will need to manually initialize the persistent bags and fetch fields using the {@link CriteriaQueryRunner#initFetchFields(Object)} method for each object in the results (for which you needto instantiate the {@link CriteriaQueryRunner} with automatic fetching switched OFF). Note that this willNOT work on the composite object itself. You need to pass an instance of the entity class to the {@link CriteriaQueryRunner#initFetchFields(Object)} method.
