| * Interface for providing a custom map-id to the compiler. |
| * <p>The map-id is inserted in the mapping file output and included in the compiler marker |
| * information. The map-id can be used to provide an key/identifier to automate the lookup of |
| * mapping file information for builds. For example, by including it in the source-file part of |
| * program stacktraces. See {@code SourceFileProvider}. |
| public interface MapIdProvider { |
| * Return the map-id content. |
| * @param environment An environment of values available for use when defining the map id. |
| * @return A non-null string that will be used as the map id. |
| String get(MapIdEnvironment environment); |
