    EventHandler handler = createHandler(adaptor);
    String regId = clientContext.getListenerService().registerListener(createCacheEntryListenerCodec(), handler);
    if (regId != null) {
        if (addToConfig) {
            cacheConfig.addCacheEntryListenerConfiguration(cacheEntryListenerConfiguration);
        }
        addListenerLocally(regId, cacheEntryListenerConfiguration);

        }
    }
}
