Usage

From source file:com.heliosapm.jmx.cache.CacheStatistics.java

/**
 * Creates a new CacheStatistics and the underlying cache from the passed {@link CacheBuilder}.
 * This call causes this CacheStatistics to register itself as the cache's removal listener
 * and removal events are broadcast as JMX notifications.
 * @param builder The guava cache builder
 * @param cacheName The assigned name for this cache
 *//* w w w.  j  a va  2 s  .c o  m*/
public CacheStatistics(final CacheBuilder<K, V> builder, final String cacheName) {
    super(SharedNotificationExecutor.getInstance(), notificationInfos);
    builder.removalListener(this);
    this.cache = builder.build();
    this.cacheName = cacheName;
    objectName = JMXHelper.objectName(JMXHelper.objectName("com.heliosapm.cache:name=" + cacheName));
