Examples of org.jboss.cache.aop.PojoCache

org.jboss.cache.aop.PojoCache
PojoCache implementation class. User should use the {@link PojoCacheIfc} interface directly toaccess the public APIs.
PojoCache is an in-memory, transactional, fine-grained, and object-oriented cache system. It differs from the typical generic cache library by operating on the pojo level directly without requiring that object to be serializable (although it does require "aspectizing" the POJO). Further, it can preserve object graph during replication or persistency. It also track the replication via fine-grained maner, i.e., only changed fields are replicated.
