Notification of Event Type Definition Changes
If your application needs to know when a Broker's event type definitions have changed, it can subscribe to the event type Adapter::refresh. Whenever this event type is received, your application will know the local event type definition cache needs to be synchronized with the Broker.
Use the BrokerTypeCache.flushCache method to cause the cache contents to be refreshed. This is an advanced method and its use is not required in most situations.
