Class OptimisticTreeCacheProvider

java.lang.Object
  org.hibernate.cache.OptimisticTreeCacheProvider

All Implemented Interfaces:

CacheProvider

public class OptimisticTreeCacheProvider
extends Object
implements CacheProvider

Support for a standalone JBossCache TreeCache instance utilizing TreeCache's optimistic locking capabilities. This capability was added in JBossCache version 1.3.0; as such this provider will only work with that version or higher.

The TreeCache instance is configured via a local config resource. The resource to be used for configuration can be controlled by specifying a value for the CONFIG_RESOURCE config property.
