Example 31 with NearCacheStats

use of com.hazelcast.nearcache.NearCacheStats in project hazelcast by hazelcast.

the class NearCacheTest method testNearCacheEntriesNotExpired_afterIMapExpiration.

/**
 * Near Cache has its own eviction/expiration mechanism, so eviction/expiration on an IMap
 * should not force any Near Cache eviction/expiration. Exceptions from this rule are direct calls to
 * <ul>
 * <li>{@link IMap#evict(Object)}</li>
 * <li>{@link IMap#evictAll()}</li>
