Constructor Detail

ReadWriteMemcachedEntityRegionAccessStrategy

public ReadWriteMemcachedEntityRegionAccessStrategy(MemcachedEntityRegion region,
                                                    org.hibernate.boot.spi.SessionFactoryOptions settings)

Method Detail

insert

public boolean insert(org.hibernate.engine.spi.SessionImplementor session,
                      Object key,
                      Object value,
                      Object version)
               throws org.hibernate.cache.CacheException

A no-op since this is an asynchronous cache access strategy.

Specified by:

insert in interface org.hibernate.cache.spi.access.EntityRegionAccessStrategy

Throws:

org.hibernate.cache.CacheException

afterInsert

public boolean afterInsert(org.hibernate.engine.spi.SessionImplementor session,
                           Object key,
                           Object value,
                           Object version)
                    throws org.hibernate.cache.CacheException

Inserts will only succeed if there is no existing value mapped to this key.

Specified by:

afterInsert in interface org.hibernate.cache.spi.access.EntityRegionAccessStrategy

Throws:

org.hibernate.cache.CacheException

update

public boolean update(org.hibernate.engine.spi.SessionImplementor session,
                      Object key,
                      Object value,
                      Object currentVersion,
                      Object previousVersion)
               throws org.hibernate.cache.CacheException

A no-op since this is an asynchronous cache access strategy.

Specified by:

update in interface org.hibernate.cache.spi.access.EntityRegionAccessStrategy

Throws:

org.hibernate.cache.CacheException

afterUpdate

public boolean afterUpdate(org.hibernate.engine.spi.SessionImplementor session,
                           Object key,
                           Object value,
                           Object currentVersion,
                           Object previousVersion,
                           org.hibernate.cache.spi.access.SoftLock lock)
                    throws org.hibernate.cache.CacheException

Updates will only succeed if this entry was locked by this transaction and exclusively this transaction for the duration of this transaction. It is important to also note that updates will fail if the soft-lock expired during the course of this transaction.

Specified by:

afterUpdate in interface org.hibernate.cache.spi.access.EntityRegionAccessStrategy

Throws:

org.hibernate.cache.CacheException

generateCacheKey

public Object generateCacheKey(Object id,
                               org.hibernate.persister.entity.EntityPersister persister,
                               org.hibernate.engine.spi.SessionFactoryImplementor factory,
                               String tenantIdentifier)

Specified by:

generateCacheKey in interface org.hibernate.cache.spi.access.EntityRegionAccessStrategy

getCacheKeyId

public Object getCacheKeyId(Object cacheKey)

Specified by:

getCacheKeyId in interface org.hibernate.cache.spi.access.EntityRegionAccessStrategy
