Method Detail

start

public final void start(Settings settings,
                        Properties properties)
                 throws CacheException

Description copied from interface: RegionFactory

Lifecycle callback to perform any necessary initialization of the underlying cache implementation(s). Called exactly once during the construction of a SessionFactoryImpl.

Specified by:

start in interface RegionFactory

Parameters:

settings - The settings in effect.

properties - The defined cfg properties

Throws:

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

stop

public final void stop()

Description copied from interface: RegionFactory

Lifecycle callback to perform any necessary cleanup of the underlying cache implementation(s). Called exactly once during SessionFactory.close().

Specified by:

stop in interface RegionFactory

isMinimalPutsEnabledByDefault

public final boolean isMinimalPutsEnabledByDefault()

Description copied from interface: RegionFactory

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

Specified by:

isMinimalPutsEnabledByDefault in interface RegionFactory

Returns:

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

getDefaultAccessType

public final AccessType getDefaultAccessType()

Description copied from interface: RegionFactory

Get the default access type for entity and collection regions.

Specified by:

getDefaultAccessType in interface RegionFactory

Returns:

This factory's default access type.

nextTimestamp

public final long nextTimestamp()

Description copied from interface: RegionFactory

Generate a timestamp.

This is generally used for cache content locking/unlocking purposes depending upon the access-strategy being used.

Specified by:

nextTimestamp in interface RegionFactory

Returns:

The generated timestamp.

buildEntityRegion

public final EntityRegion buildEntityRegion(String regionName,
                                            Properties properties,
                                            CacheDataDescription metadata)
                                     throws CacheException

Description copied from interface: RegionFactory

Build a cache region specialized for storing entity data.

Specified by:

buildEntityRegion in interface RegionFactory

Parameters:

regionName - The name of the region.

properties - Configuration properties.

metadata - Information regarding the type of data to be cached

Returns:

The built region

Throws:

CacheException - Indicates problems building the region.

buildCollectionRegion

public final CollectionRegion buildCollectionRegion(String regionName,
                                                    Properties properties,
                                                    CacheDataDescription metadata)
                                             throws CacheException

buildQueryResultsRegion

public final QueryResultsRegion buildQueryResultsRegion(String regionName,
                                                        Properties properties)
                                                 throws CacheException
