Field Summary

static String	CACHE_CONFIG_PATH The system property specifying the path to the cache configuration used to configure the hibernate L2 caches.
protected static String	DEFAULT_CACHE_CONFIG_PATH The cache configuration file that defines Coherence caches for Hibernate
protected static String	PREFIX The prefix for all provider-specific system properties

Constructor Summary

CoherenceCacheProvider()

Method Summary

Cache	buildCache(String sRegionName, Properties properties) Returns a Hibernate cache region (creating a clustered NamedCache instance if necessary).
protected ConfigurableCacheFactory	getCacheFactory() Get the ConfigurableCacheFactory instance
protected NamedCache	getNamedCache(String sName) Get a NamedCache instance given a cache name.
boolean	isMinimalPutsEnabledByDefault() Indicates whether minimal puts are enabled by default.
long	nextTimestamp() Returns the current timestamp.
protected void	setCacheFactory(ConfigurableCacheFactory factory) Set the ConfigurableCacheFactory instance
void	start(Properties properties) Initializes the Coherence cache provider and pre-starts Coherence.
void	stop() Stops the Coherence cache provider and frees local resources.

CoherenceCacheProvider

public CoherenceCacheProvider()

Method Detail

buildCache

public Cache buildCache(String sRegionName,
                        Properties properties)

Returns a Hibernate cache region (creating a clustered NamedCache instance if necessary).

Parameters:

sRegionName - a Hibernate cache region name

properties - not used by this implementation

Returns:

a Hibernate cache region reference

nextTimestamp

public long nextTimestamp()

Returns the current timestamp.

Returns:

the current timestamp

start

public void start(Properties properties)
           throws CacheException

Initializes the Coherence cache provider and pre-starts Coherence.

Parameters:

properties - configuration properties

Throws:

CacheException - thrown if there are configuration errors

stop

public void stop()

Stops the Coherence cache provider and frees local resources.

isMinimalPutsEnabledByDefault

public boolean isMinimalPutsEnabledByDefault()

Indicates whether minimal puts are enabled by default. This allows Hibernate to use extra gets to minimize the number of puts.

Returns:

a boolean indicating whether minimal puts are the default

getCacheFactory

protected ConfigurableCacheFactory getCacheFactory()

Get the ConfigurableCacheFactory instance

Returns:

the ConfigurableCacheFactory

setCacheFactory

protected void setCacheFactory(ConfigurableCacheFactory factory)

Set the ConfigurableCacheFactory instance

Parameters:

factory - the ConfigurableCacheFactory instance

getNamedCache

protected NamedCache getNamedCache(String sName)

Get a NamedCache instance given a cache name.

Parameters:

sName - the name of the NamedCache

Returns:

the NamedCache instance
