Method Detail

getBackingMap

                                      java.lang.String fieldName)

Returns the backing store for the specified Map field.

newSCOInstance

public abstract SCO newSCOInstance(java.lang.Object owner,
                                   java.lang.String fieldName,
                                   PersistentMap backing)

Returns a new SCO Map instance that is unloaded. The returned instance is owned by the specified owner but has not been assigned to the corresponding field.

Initially, the contents of the map are not necessarily loaded in memory. Its contents are partially or fully loaded from the backing store in response to application method calls on the map.

Parameters:

owner - The first-class object that will own the new second-class object.

fieldName - The name of the field in the owning object.

backing - The backing store for the map.

Returns:

A new SCO instance.
