@Deprecated public class InMemPersistenceManager extends AbstractPersistenceManager
InMemPersistenceManager
is a very simple HashMap
-based
PersistenceManager
for Jackrabbit that keeps all data in memory
and that is capable of storing and loading its contents using a simple custom
binary serialization format (see Serializer
).
It is configured through the following properties:
initialCapacity
: initial capacity of the hash map used to store the dataloadFactor
: load factor of the hash map used to store the datapersistent
: if true
the contents of the hash map
is loaded on startup and stored on shutdown;
if false
