Method Detail

clear	back to summary
public void clear() Implements org.eclipse.persistence.jpa.JpaCache.clear. ADVANCED: Resets the entire Object cache, and the Query cache. Note Be careful using this method. This method blows away both this session's and its parent's caches. This includes the server cache or any other cache. This throws away any Objects that have been read in. Extreme caution should be used before doing this because Object identity will no longer be maintained for any Objects currently read in. This should only be called if the application knows that it no longer has references to Objects held in the cache. Annotations @Override
