- All Implemented Interfaces:
FieldManager
public class LoadFieldManager extends AbstractFetchDepthFieldManager
Field Manager to handle loading all fields of all objects in the fetch plan. The method in JDOStateManager only loads the fields for that object and so will only load the DFG fields for objects (hence omitting any non-DFG fields that are in the FetchPlan that have been omitted due to lazy-loading).
