Class JMSCacheImpl
java.lang.Object
com.bankframe.services.cache.GenericCache
com.bankframe.services.cache.JMSCacheImpl
- All Implemented Interfaces:
- Cache, JMSCache, NamedCache, PersistentCache, Map
public class JMSCacheImpl
- extends GenericCache
- implements JMSCache
The JMSCacheImpl class provides generic caching functionality using a distributed cache within a
clustered environment. It implements the java.util.Map
interface. This class uses
the supplied Map implementation to maintain consistency between the cache and the data store. The
supplied Map implementation must store and read its contents from some permanent data store. An
object will remain in the cache until it expires. When the object expires is determined by the
CachePolicy object. Once an object has been removed from the local cache a message is generted
and put on a JMS Topic. This message will be read by other instances in the cluster via the
Message Driven Bean (MDB) com.bankframe.services.cache.JMSListener. This MDB will remove the
entry supplied in the message from the local cache on that cluster node.
