| 5 // Contains the BlimpMessage proto which frames all messages sent over Blimp | |
| 6 // subchannels. BlimpMessage protos are serialized and transmitted over the | |
| 7 // wire to the Blimplet server. | |
| 8 // | |
| 9 // Each BlimpMessage has a few identifying fields which provide the browser | |
| 10 // session and tab ID as context. The message details are stored in a | |
| 11 // feature-specific field (see field IDs 1000 and onward). | |
| 12 // The |type| field tells the receiving end how the BlimpMessage should | |
| 13 // be unpacked and which component it should be routed to. | |
| 14 // | |
| 15 // CONVENTIONS: | |
| 16 // * A BlimpMessage can contain only one feature message. | |
| 17 // * Feature message protos are placed in their own files. | |
| 18 // * Features are applied to unidirectional channels. Client->server and | |
| 19 // server->client channels for a component should be broken out as distinct | |
| 20 // features, even if they are conceptually similar. | |
