Constructor Detail

ReadWriteMemcachedNaturalIdRegionAccessStrategy

public ReadWriteMemcachedNaturalIdRegionAccessStrategy(MemcachedNaturalIdRegion region,
                                                       org.hibernate.boot.spi.SessionFactoryOptions settings,
                                                       org.hibernate.cache.spi.CacheDataDescription metadata)

Method Detail

insert

public boolean insert(org.hibernate.engine.spi.SessionImplementor session,
                      Object key,
                      Object value)
               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.NaturalIdRegionAccessStrategy

Throws:

org.hibernate.cache.CacheException

afterInsert

public boolean afterInsert(org.hibernate.engine.spi.SessionImplementor session,
                           Object key,
                           Object value)
                    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.NaturalIdRegionAccessStrategy

Throws:

org.hibernate.cache.CacheException

update

public boolean update(org.hibernate.engine.spi.SessionImplementor session,
                      Object key,
                      Object value)
               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.NaturalIdRegionAccessStrategy

Throws:

org.hibernate.cache.CacheException

afterUpdate

public boolean afterUpdate(org.hibernate.engine.spi.SessionImplementor session,
                           Object key,
                           Object value,
                           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.NaturalIdRegionAccessStrategy

Throws:

org.hibernate.cache.CacheException

generateCacheKey

public Object generateCacheKey(Object[] naturalIdValues,
                               org.hibernate.persister.entity.EntityPersister persister,
                               org.hibernate.engine.spi.SessionImplementor session)

Specified by:

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

getNaturalIdValues

public Object[] getNaturalIdValues(Object cacheKey)

Specified by:

getNaturalIdValues in interface org.hibernate.cache.spi.access.NaturalIdRegionAccessStrategy
