Class SmartMemberListCache<K,V>

java.lang.Object
  mondrian.rolap.SmartMemberListCache<K,V>

public class SmartMemberListCache<K,V>
extends Object

Uses a SmartCache to store lists of members, where the key depends on a SqlConstraint.

Example 1

   select ...
   [Customer].[Name].members on rows
   ...
 

Example 2

   select ...
   NON EMPTY [Customer].[Name].members on rows
   ...
   WHERE ([Store#14], [Product].[Product#1])
 

The first set, all customers are computed, in the second only those, who have bought Product#1 in Store#14. We want to put both results into the cache. Then the key for the cache entry is the Level that the members belong to plus the costraint that restricted the amount of members fetched. For Level.Members the key consists of the Level and the cacheKey of the SqlConstraint
