JDO Interface

DataStoreCache

Many JDO implementations allow instances to be cached in a second-level cache, and allow direct management of the cache by knowledgeable applications. This interface standardizes this behavior.
Since:
JDO 2.0

Public Methods

void evict(Object oid)
Evict the parameter instance from the second-level cache.
Parameters:
oid - the object id of the instance to evict.
Since:
JDO 2.0
void evictAll()
Evict the parameter instances from the second-level cache.
All instances in the PersistenceManager's cache are evicted from the second-level cache.
Since:
JDO 2.0
void evictAll(Collection oids)
Evict the parameter instances from the second-level cache.
Parameters:
oids - the object ids of the instance to evict.
