Examples of PersistenceAdapter

nexj.core.persistence.PersistenceAdapter
Interface implemented by components, which translate an OO query to an engine-specific request and execute it.
org.activemq.store.PersistenceAdapter
Adapter to the actual persistence mechanism used with ActiveMQ @version $Revision: 1.1.1.1 $
org.apache.activemq.store.PersistenceAdapter
Adapter to the actual persistence mechanism used with ActiveMQ @version $Revision: 1.3 $
org.codehaus.activemq.store.PersistenceAdapter
Adapter to the actual persistence mechanism used with ActiveMQ @version $Revision: 1.3 $
org.exolab.jms.persistence.PersistenceAdapter
This adapter is a wrapper class around the persistency mechanism. It isolates the client from the working specifics of the database, by providing a simple straight forward interface. Future changes to the database will only require changes to the adapter. @version $Revision: 1.2 $ $Date: 2005/03/18 04:05:52 $ @author Jim Mourikis @see org.exolab.jms.persistence.RDBMSAdapter
org.globus.workspace.persistence.PersistenceAdapter
TODO: each module implementation needs to encapsulate its own persistence, the persistence package will go away entirely
