Interface RegionFactory

All Superinterfaces:
Serializable, Service, Stoppable
All Known Subinterfaces:
RegionFactory
All Known Implementing Classes:
AbstractRegionFactory, NoCachingRegionFactory, RegionFactoryTemplate
public interface RegionFactory extends Service, Stoppable
Contract for building second-level cache regions, including regions dedicated to storing:

Implementors should define a constructor in one of two forms:

  • MyRegionFactoryImpl(java.util.Properties)
  • MyRegionFactoryImpl()

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

A RegionFactory may be selected using the property "hibernate.cache.region.factory_class".

  • Method Details

    • start

      void start(SessionFactoryOptions settings, Map<String,Object> configValues) throws CacheException
      Lifecycle callback to perform any necessary initialization of the underlying cache provider. Called exactly once during the construction of a SessionFactoryImpl.
      Parameters:
      settings - The settings in effect.
      configValues - The available config values
      Throws:
      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?
      Returns:
      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. It's also expected that this be the value used by the CacheTransactionSynchronization created by this RegionFactory.
      API Note:
      This "timestamp" need not be related to timestamp in the Date.getTime()/System.currentTimeMillis() sense. It just needs to be an incrementing value.

    • getTimeout

      default long getTimeout()

    • buildDomainDataRegion

      DomainDataRegion buildDomainDataRegion(DomainDataRegionConfig regionConfig, DomainDataRegionBuildingContext buildingContext)
      Create a named Region for holding domain model data
      Parameters:
      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)
      Create a named Region for holding query result sets.

    • buildTimestampsRegion

      TimestampsRegion buildTimestampsRegion(String regionName, SessionFactoryImplementor sessionFactory)
      Create a named Region for holding timestamps used to determine when a cached query result set is stale.
