Constructor Details

CoherenceReadWriteCollectionAccess

public CoherenceReadWriteCollectionAccess(org.hibernate.cache.spi.DomainDataRegion domainDataRegion,
 org.hibernate.cache.spi.support.DomainDataStorageAccess domainDataStorageAccess,
 Comparator<?> versionComparator)

Complete constructor.

Parameters:

domainDataRegion - the domain data region

domainDataStorageAccess - the domain data storage access

versionComparator - the version comparator

Method Details

generateCacheKey

public Object generateCacheKey(Object id,
 org.hibernate.persister.collection.CollectionPersister persister,
 org.hibernate.engine.spi.SessionFactoryImplementor sessionFactoryImplementor,
 String tenantIdentifier)

Specified by:

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

getCacheKeyId

public Object getCacheKeyId(Object cacheKey)

Specified by:

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

getAccessType

public org.hibernate.cache.spi.access.AccessType getAccessType()

Specified by:

getAccessType in interface org.hibernate.cache.spi.access.CachedDomainDataAccess

get

public Object get(org.hibernate.engine.spi.SharedSessionContractImplementor session,
 Object key)
           throws org.hibernate.cache.CacheException

Overrides:

get in class AbstractCoherenceEntityDataAccess

Throws:

org.hibernate.cache.CacheException

lockItem

public org.hibernate.cache.spi.access.SoftLock lockItem(org.hibernate.engine.spi.SharedSessionContractImplementor session,
 Object key,
 Object version)
                                                 throws org.hibernate.cache.CacheException

Overrides:

lockItem in class AbstractCoherenceEntityDataAccess

Throws:

org.hibernate.cache.CacheException

putFromLoad

public boolean putFromLoad(org.hibernate.engine.spi.SharedSessionContractImplementor session,
 Object key,
 Object value,
 Object version,
 boolean minimalPutOverride)
                    throws org.hibernate.cache.CacheException

Overrides:

putFromLoad in class AbstractCoherenceEntityDataAccess

Throws:

org.hibernate.cache.CacheException

unlockItem

public void unlockItem(org.hibernate.engine.spi.SharedSessionContractImplementor session,
 Object key,
 org.hibernate.cache.spi.access.SoftLock lock)
                throws org.hibernate.cache.CacheException

Overrides:

unlockItem in class AbstractCoherenceEntityDataAccess

Throws:

org.hibernate.cache.CacheException

afterInsert

protected boolean afterInsert(Object key,
 CoherenceRegionValue value)

Coherence-based implementation of behavior common to: 1. org.hibernate.cache.spi.access.EntityRegionAccessStrategy.afterInsert(Object key, Object value, Object version) and 2. org.hibernate.cache.spi.access.NaturalIdRegionAccessStrategy.afterInsert(Object key, Object value). The only difference in implementation is that the cache value in a NaturalIdRegion will have a null version object.

Parameters:

key - the key at which to insert a value

value - the value to insert

Returns:

a boolean indicating whether cache contents were modified

afterUpdate

protected boolean afterUpdate(Object key,
 CoherenceRegionValue value,
 org.hibernate.cache.spi.access.SoftLock softLock)

Coherence-based implementation of behavior common to: 1. org.hibernate.cache.spi.access.EntityRegionAccessStrategy.afterUpdate(Object key, Object value, Object currentVersion, Object previousVersion, SoftLock lock) and 2. org.hibernate.cache.spi.access.NaturalIdRegionAccessStrategy.afterUpdate(Object key, Object value, SoftLock lock). The only difference in implementation is that the cache value in a NaturalIdRegion will have a null version object.

Parameters:

key - the key at which to insert a value

value - the value to insert

softLock - the softLock acquired in an earlier lockItem call with the argument key

Returns:

a boolean indicating whether cache contents were modified
