Class RegionManager

java.lang.Object
  org.jboss.cache.marshall.RegionManager

public class RegionManager
extends java.lang.Object

Factory to create region from configuration, to track region, and to resolve naming conflict for regions. Note that in addition to user-specified regions, there is also a global cache _default_ region that covers everything else.

Note that this is almost identical to the one used in eviction policy. We will need to refactor them in the future for everyone to use.
