This package provides classes implementing caching within JPOX.
There are 2 caches in JPOX.
The first is within the PersistenceManager
and is the Level 1 Cache. There are 3 available implementations
of a Level 1 Cache here :- SoftRefCache, WeakRefCache
and HardRefCache. They provide varying degrees of object retention
during the garbage collection process.
The second is across multiple PersistenceManagers within the same
PersistenceManagerFactory, and is the Level 2 Cache. There is
one implementation of a Level 2 Cache here :- DefaultLevel2Cache.
Alternatively, there is the TangosolCache plugin that can be used
in conjunction with the commercial Tangosol Coherence product.
