| // The implementation of the open flow agent (ofagent) uses a GRPC connection |
| // to VOLTHA accross several implementaton packages including the ofagent and |
| // openflow packages. This GRPC connection is shared through packages and type |
| // instances via injection. |
| // |
| // As the ofagent executes within a micro-service environment it is |
| // possible that the GRPC connection is reset (re-established). When the connection |
| // is re-established, because injection is used, the new value needs to be |
| // re-injected across the implementation. |
| // |
| // To help simply the re-injection or value change scenario a holder for the |
| // GRPC connection is established so that the reference to the holder can |
| // stay [sic] consistant over the lifetime of the ofagent while the underlying |
| // GRPC connection can change without walking the entire runtime structure. |
