public static interface RolapMemberBase.PropertyValueMapFactory
Interface definition for the pluggable factory used to decide
which implementation of
Map to use to store
property string/value pairs for member properties.
This permits tuning for performance, memory allocation, etcetera. For example, if a member belongs to a level which has 10 member properties a HashMap may be preferred, while if the level has only two member properties a Flat3Map may make more sense.
