  org.hibernate.cache.StandardQueryCache

All Implemented Interfaces:

QueryCache

public class StandardQueryCache
extends Object

The standard implementation of the Hibernate QueryCache interface. This implementation is very good at recognizing stale query results and and re-running queries when it detects this condition, recaching the new results.
