java.lang.Objectnet.sf.ehcache.store.AbstractStore
net.sf.ehcache.store.compound.CompoundStore
net.sf.ehcache.store.compound.impl.DiskPersistentStore
public final class DiskPersistentStore
Implements a persistent-to-disk store.
All new elements are automatically scheduled for writing to disk. In addition the store will cache Elements in memory up to the in-memory capacity.
