Method Detail

start

public void start(Settings settings,
         java.util.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 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 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 AccessType getDefaultAccessType()

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 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.

getCacheProvider

public CacheProvider getCacheProvider()

buildEntityRegion

public EntityRegion buildEntityRegion(java.lang.String regionName,
                             java.util.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 CollectionRegion buildCollectionRegion(java.lang.String regionName,
                                     java.util.Properties properties,
                                     CacheDataDescription metadata)
                                       throws CacheException

Description copied from interface: RegionFactory

Build a cache region specialized for storing collection data.

Specified by:

buildCollectionRegion 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.

buildQueryResultsRegion

public QueryResultsRegion buildQueryResultsRegion(java.lang.String regionName,
                                         java.util.Properties properties)
                                           throws CacheException

Description copied from interface: RegionFactory

Build a cache region specialized for storing query results

Specified by:

buildQueryResultsRegion in interface RegionFactory

Parameters:
