How to use

invalidateAll

method

in

com.bazaarvoice.emodb.cachemgr.api.CacheHandle

@Override

      // then subsequently added to _cacheRegistry in createCache(), making it possible for a value to
      // be cached but not invalidated on this call.  However, to avoid this issue all caches used by
      // this manager are pre-created in ApiKeyRealm.onInit(), so in practice this can never happen.
