I wrote such a Linker :
/**
* This GWT linker creates a properties file which can be used to
resolve Permutation Strong name given UserAgent and locale.
*
* @author Etienne Lacazedieu
*
*/
@LinkerOrder(Order.PRE)
public class StrongNameOracleLinker extends AbstractLinker {
public static final String STRONGNAME_FILE = "permutation.properties";
@Override
public String getDescription() {
return "PermutationStrongName Oracle linker";
}
@Override
public ArtifactSet link(TreeLogger logger, LinkerContext context,
ArtifactSet artifacts) throws UnableToCompleteException {
artifacts = new ArtifactSet(artifacts);
ByteArrayOutputStream out = new ByteArrayOutputStream();
String permutation = null;
String locale = null;
String userAgent = null;
SelectionProperty selectionProperty = null;
Properties props = new Properties();
for (CompilationResult result :
artifacts.find(CompilationResult.class)) {
permutation = result.getStrongName();
SortedSet<SortedMap<SelectionProperty, String>>
propertiesMap = result.getPropertyMap();
for (SortedMap<SelectionProperty, String> sm : propertiesMap) {
for (Map.Entry<SelectionProperty, String> e : sm.entrySet()) {
selectionProperty = e.getKey();
if ("locale".equals(selectionProperty.getName())) {
locale = e.getValue();
}
if ("user.agent".equals(selectionProperty.getName())) {
userAgent = e.getValue();
}
}
}
props.setProperty(userAgent + "." + locale, permutation);
}
try {
props.store(out, "StrongNameOracle properties file");
} catch (IOException e) { // Should generally not happen
logger.log(TreeLogger.ERROR, "Unable to store deRPC data", e);
throw new UnableToCompleteException();
}
SyntheticArtifact a = emitBytes(logger, out.toByteArray(),
STRONGNAME_FILE);
artifacts.add(a);
return artifacts;
}
}
