Class LoadFieldManager
java.lang.Object
org.datanucleus.store.fieldmanager.AbstractFieldManager
org.datanucleus.store.fieldmanager.AbstractFetchDepthFieldManager
org.datanucleus.store.fieldmanager.LoadFieldManager
- All Implemented Interfaces:
FieldManager
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).
