@ThreadSafe public class GoogleCacheInstruments extends Object
Instrumentation
. This is usually called from within a component's "start" callback
(e.g. JIRA's Startable.start()
or Spring's InitializingBean.afterPropertiesSet()
). Example:
new GoogleCacheInstruments("cacheName").addCache(this.cacheOfThings).install();Remember to call
GoogleCacheInstruments.uninstall()
in the destruction callbacks, or you will cause a memory
leak.
This class is thread-safe.
