Examples of org.apache.openjpa.datacache.ConcurrentDataCache

org.apache.openjpa.datacache.ConcurrentDataCache
A {@link DataCache} implementation that is optimized for concurrentaccess. When the cache fills up, values to remove from cache are chosen randomly. Due to race conditions, it is possible that a get call might not return a cached instance if that instance is being transferred between internal datastructures. @since 0.4.0
