public void setSource(OptimisticCacheSource source)
OptimisticCacheEntityPersister.
Made available to the cache so that it can access certain information
about versioning strategy.
setSource in interface OptimisticCachesource - The source.
public void writeInsert(Object key,
Object value,
Object currentVersion)
OptimisticCacheCacheConcurrencyStrategy.insert(java.lang.Object, java.lang.Object, java.lang.Object) processing for
transactional strategies. Indicates we have just performed an insert
into the DB and now need to cache that entity's data.
writeInsert in interface OptimisticCachekey - The cache key.value - The data to be cached.currentVersion - The entity's version; or null if not versioned.
public void writeUpdate(Object key,
Object value,
Object currentVersion,
Object previousVersion)
OptimisticCacheCacheConcurrencyStrategy.update(java.lang.Object, java.lang.Object, java.lang.Object, java.lang.Object) processing for
transactional strategies. Indicates we have just performed an update
against the DB and now need to cache the updated state.
writeUpdate in interface OptimisticCachekey - The cache key.value - The data to be cached.currentVersion - The entity's current versionpreviousVersion - The entity's previous version (before the update);
or null if not versioned.
public void writeLoad(Object key,
Object value,
Object currentVersion)
OptimisticCacheCacheConcurrencyStrategy.put(java.lang.Object, java.lang.Object, long, java.lang.Object, java.util.Comparator, boolean) processing for
transactional strategies. Indicates we have just loaded an entity's
state from the database and need it cached.
writeLoad in interface OptimisticCachekey - The cache key.value - The data to be cached.currentVersion - The entity's version; or null if not versioned.
