接口 RegionFactory

所有超级接口:

Serializable, Service, Stoppable

所有已知子接口:

RegionFactory

所有已知实现类:

AbstractRegionFactory, NoCachingRegionFactory, RegionFactoryTemplate

public interface RegionFactory
extends Service, Stoppable

Contract for building second level cache regions.

Implementors should define a constructor in one of two forms:

• MyRegionFactoryImpl(Properties)
• MyRegionFactoryImpl()

Use the first when we need to read config properties prior to start(org.hibernate.boot.spi.SessionFactoryOptions, java.util.Map) being called.

方法详细资料

start

void start(SessionFactoryOptions settings,
           Map configValues)
    throws CacheException

Lifecycle callback to perform any necessary initialization of the underlying cache provider. Called exactly once during the construction of a SessionFactoryImpl.

参数:

settings - The settings in effect.

configValues - The available config values

抛出:

CacheException - Indicates problems starting the L2 cache impl; considered as a sign to stop SessionFactory building.

isMinimalPutsEnabledByDefault

boolean isMinimalPutsEnabledByDefault()

By default should we perform "minimal puts" when using this second level cache implementation?

返回:

True if "minimal puts" should be performed by default; false otherwise.

getDefaultAccessType

AccessType getDefaultAccessType()

Get the default access type for any "user model" data

qualify

String qualify(String regionName)

createTransactionContext

default CacheTransactionSynchronization createTransactionContext(SharedSessionContractImplementor session)

nextTimestamp

long nextTimestamp()

Generate a timestamp. This value is generally used for purpose of locking/unlocking cache content depending upon the access-strategy being used. The intended consumer of this method is the Session to manage its SharedSessionContractImplementor.getTransactionStartTimestamp() value. It is also expected that this be the value used for this's RegionFactory's CacheTransactionContext

getTimeout

default long getTimeout()

buildDomainDataRegion

DomainDataRegion buildDomainDataRegion(DomainDataRegionConfig regionConfig,
                                       DomainDataRegionBuildingContext buildingContext)

Create a named Region for holding domain model data

参数:

regionConfig - The user requested caching configuration for this Region

buildingContext - Access to delegates useful in building the Region

buildQueryResultsRegion

QueryResultsRegion buildQueryResultsRegion(String regionName,
                                           SessionFactoryImplementor sessionFactory)

buildTimestampsRegion

TimestampsRegion buildTimestampsRegion(String regionName,
                                       SessionFactoryImplementor sessionFactory)
