Examples of org.jboss.cache.Region

org.jboss.cache.Region
Defines characteristics such as class loading and eviction of {@link org.jboss.cache.Node}s belonging to a Region in a {@link Cache}. A Region is described by an {@link #getFqn() Fqn} relative to the root of the cache.All nodes and child nodes of this Fqn belong to this region.
If a region is to be recognised as an eviction region (region of type {@link Type#EVICTION} thenit must have an {@link org.jboss.cache.config.EvictionRegionConfig} set using {@link #setEvictionRegionConfig(org.jboss.cache.config.EvictionRegionConfig)}.
Similarly, to be recognised as a marshalling region (region of type {@link Type#MARSHALLING} then it must have a{@link ClassLoader} registered using {@link #registerContextClassLoader(ClassLoader)}.
Note that a single region can be both an eviction and marshalling region at the same time.
