Class AbstractMapCacheProvider

java.lang.Object
  org.openspaces.hibernate.cache.AbstractMapCacheProvider

All Implemented Interfaces:

org.hibernate.cache.CacheProvider

Direct Known Subclasses:

SimpleMapCacheProvider, TransactionalMapCacheProvider

public abstract class AbstractMapCacheProvider
extends Object
implements org.hibernate.cache.CacheProvider

Base class for pure Space (no OpenSpaces components) Hibernate cache provider. Uses the property gigaspace.hibernate.cache.url to retrieve the Space/Cache url. Also passes the properites object to the Space/Cache construction allowing to fully configure the cache using Hibernate cache proeprties (for example, have "xpath" configuration set there).

Allows to configure the time to live of cache entries within the Space using the gigaspace.hibernate.cache.timeToLive property. Defaults to Long.MAX_VALUE.

Stops the local cache when this cache provider stops. Also stops the master Space if it was started in an embedded mode.

Method Detail

start

public void start(Properties properties)
           throws org.hibernate.cache.CacheException

Starts the pure GigaSpace Hibernate cache provider. Uses gigaspace.hibernate.cache.url property to fetch the cache url. Also passes the proeprties to the CacheFinder.find(String, java.util.Properties) so any additional Space related properties can be set.

Specified by:

start in interface org.hibernate.cache.CacheProvider

Throws:

org.hibernate.cache.CacheException

doStart

protected void doStart(Properties properties)
                throws org.hibernate.cache.CacheException

Subclasses can implement this method in order to perform additional operations during startup.

Throws:

org.hibernate.cache.CacheException

stop

public void stop()

Stops the local cache. If the master Space was started in embedded mode, will also stop the master space.

Specified by:

stop in interface org.hibernate.cache.CacheProvider

doStop

protected void doStop()

nextTimestamp

public long nextTimestamp()

Specified by:

nextTimestamp in interface org.hibernate.cache.CacheProvider

isMinimalPutsEnabledByDefault

public boolean isMinimalPutsEnabledByDefault()

Specified by:

isMinimalPutsEnabledByDefault in interface org.hibernate.cache.CacheProvider
