Examples of CacheIndex

com.cetsoft.imcache.cache.search.index.CacheIndex
The Interface CacheIndex is a data structure that improves the speed of data retrieval operations on a cache at the cost of additional writes and the use of more storage space to maintain the extra copy of data. Indexes are used to quickly locate data without having to search every object in a cache.
org.eclipse.persistence.descriptors.CacheIndex

Purpose: Define a secondary index on the cache. @see CachePolicy
