In PojoCache, there are 3 core APIs for for pojo management and one additional one for querying. They will be fully discussed here. Note that we have stressed that the management aspect of these APIs. This is because we expect most of the time, you only use these APIs to attach, detach, and retrieve the POJO from the cache system. After that, a user should operate on that POJO reference directly without worrying about replication and/or persistency aspects.
