The BrokerAdminClient.setEventAdminTypeDefs method allows your client application to modify or create several event type definitions in a single method invocation. Your application must first obtain and modify (or create and initialize) the desired BrokerAdminTypeDef objects and provide them as input to this method. If any of the BrokerAdminTypeDef objects you provide do not exist on the Broker, they will be created. If any of the event type definitions already exist on the Broker, they will be updated
