Examples of FetchPlan

javax.jdo.FetchPlan
Fetch groups are activated using methods on this interface. An instance of this interface can be obtained from {@link PersistenceManager#getFetchPlan}, {@link Extent#getFetchPlan}, and {@link Query#getFetchPlan}. When a Query or Extent is retrieved from a PersistenceManager, its FetchPlan is initialized to the same settings as that of the PersistenceManager. Subsequent modifications of the Query or Extent's FetchPlan are not reflected in the FetchPlan of the PersistenceManager. @version 2.0 @since 2.0

The fetch plan allows you to dynamically alter eager fetching configuration and other aspects of data loading. @author Abe White @author Pinaki Poddar @since 0.4.1 @published
org.datanucleus.FetchPlan
FetchPlan for fields for use internally. A FetchPlan has a series of FetchPlanForClass objects being the fetch plan for particular classes. Each FetchPlanForClass defines a series of fields of that class that are part of the fetch plan. There are two types of fetch groups under consideration here.
- Static fetch groups, defined in MetaData (XML/Annotations).
- Dynamic fetch groups, defined via an API.
