Example 6 with ExpiryPolicy

use of org.cache2k.expiry.ExpiryPolicy in project cache2k by cache2k.

the class ListenerTest method asyncHalfExpiredAfterUpdate.

/**
 * Expire time is load time if entry is modified, yields: Expiry listener is called. Entry
 * stays in the cache, we need to implement the removal
 */

public void asyncHalfExpiredAfterUpdate() {
    final AtomicInteger _expireCallCount = new AtomicInteger();
