Class SingleTypeFieldManager

java.lang.Object
org.datanucleus.store.fieldmanager.SingleTypeFieldManager
All Implemented Interfaces:
FieldManager
public class SingleTypeFieldManager extends Object implements FieldManager
A simple field manager that stores/fetches a single field value per type in memory.

Calls to the store methods save the value in a local field; calls to the fetch methods return the previously stored value for that type, or the "empty" default value if nothing has been stored.

The field number arguments to each method are ignored.
