Method Detail

acceptRequestedEvent

void acceptRequestedEvent(int packExtPos,
                          boolean cacheHit,
                          long loadMicros,
                          long bytes,
                          Duration lastEvictionDuration)

                                Duration lastEvictionDuration)

Accept an event of an index evicted from cache.
