| * ***************************************************************************** |
| * Below are all of the individual atoms that are logged by Android via statsd |
| * and Westworld. |
| * |
| * RULES: |
| * - The field ids for each atom must start at 1, and count upwards by 1. |
| * Skipping field ids is not allowed. |
| * - These form an API, so renaming, renumbering or removing fields is |
| * not allowed between android releases. (This is not currently enforced, |
| * but there will be a tool to enforce this restriction). |
| * - The types must be built-in protocol buffer types, namely, no sub-messages |
| * are allowed (yet). The bytes type is also not allowed. |
| * - The CamelCase name of the message type should match the |
| * underscore_separated name as defined in StatsEvent. |
| * - If an atom represents work that can be attributed to an app, there can |
| * be exactly one WorkSource field. It must be field number 1. |
| * - A field that is a uid should be a string field, tagged with the [xxx] |
| * annotation. The generated code on android will be represented by UIDs, |
| * and those UIDs will be translated in xxx to those strings. |
| * |
| * CONVENTIONS: |
| * - Events are past tense. e.g. ScreenStateChanged, not ScreenStateChange. |
| * - If there is a UID, it goes first. Think in an object-oriented fashion. |
