Hi Icaro, [1] actually defines the grouping, rpc and notifications, but [2] provides the high level tree structure where these grouping are augmented. There are two ways you can do Flow related CRUD operations
(a) Through Data Store : In this case you use [2] to store the flow in config data store and that eventually go down to the switch using the FRM application. Also Statistics manager fetch the installed flow and populate the same tree in operational data store part. That way you can "get" the flow that is really installed on the switch. (b) Through RPC : To use this method you need to use the RPC defined in [1] to do Create/Delete/Update operations, but you will have to use RPC defined in [3] to get the flow from switch. Although these API's are async API, so once you make a call to fetch the flow, you will have to listen to notification [4] to get the statistics and make sure that flow is present in those statistics ( it's a job done by statistics-manager for approach [a].
