public class ColumnRegionObjectWithDictionary<T,ATTR extends Values>
extends InvalidatableRegion<ATTR>
implements ColumnRegionObject<T,ATTR>, Page.WithDefaults<ATTR>

A Column region for objects that is backed by a dictionary of values. Note that the dictionary keys are in the flat address space within the region [0,regionSize), not of the region itself.
