Class EhCacheRegionFactory

java.lang.Object
  net.sf.ehcache.hibernate.EhCacheRegionFactory
      org.onebusaway.container.spring.ehcache.EhCacheRegionFactory

All Implemented Interfaces:

org.hibernate.cache.RegionFactory

public class EhCacheRegionFactory
extends net.sf.ehcache.hibernate.EhCacheRegionFactory

A Hibernate EhCacheRegionFactory implementation that supports directly setting the CacheManager from an existing instance. This allows us to dynamically configure out CacheManager using Spring and then pass it into Hibernate. Unfortunately, the EhCacheRegionFactory cannot be passed as an instance object to Hibernate, but instead as a class name to be created by Hibernate itself. Thus, there is no easy way to connect it the Spring application context. As a kludge to get around that, we have a static setStaticCacheManagerInstance(CacheManager) that can be called from the Spring application context config to supply the CacheManager instance. It's a hack, but I don't see any way around it.
