Class TimestampsRegionImpl

java.lang.Object
  org.hibernate.cache.jbc2.BasicRegionAdapter
      org.hibernate.cache.jbc2.TransactionalDataRegionAdapter
          org.hibernate.cache.jbc2.timestamp.TimestampsRegionImpl

All Implemented Interfaces:

GeneralDataRegion, Region, TimestampsRegion, TransactionalDataRegion

public class TimestampsRegionImpl
extends TransactionalDataRegionAdapter
implements TimestampsRegion

Defines the behavior of the timestamps cache region for JBossCache 2.x. TODO Need to define a way to ensure asynchronous replication events do not result in timestamps moving backward, while dealing with the fact that the normal sequence of UpdateTimestampsCache.preinvalidate() then UpdateTimestampsCache.invalidate() will result in 2 calls to put() with the latter call having an earlier timestamp.
