Class NaiveEternalCacheManager

java.lang.Object
  com.endeca.portal.mdex.cache.NaiveEternalCacheManager

All Implemented Interfaces:

MDEXCacheManager

public class NaiveEternalCacheManager
extends java.lang.Object
implements MDEXCacheManager

EXPERIMENTAL AND UNSUPPORTED!!!! This cache manager uses ehcache to store query results for as long as possible. Configure ehcache using Liferay's configuration files. This class is GUARANTEED to return incorrect results in the face of data updates to the MDEX Engine. Furthermore, due to the toJSON/toXML methods required to generate a cache key, this manager is expensive and slow. Finally, since MDEX Engine queries are extremely varied, this class is likely to be a resource hog, to the point of hurting overall performance of your server. This class is provided as a proof of concept only.
