Hi All,
I am trying to use deferred binding to generate implementation in run-time
and encountered with one problem. I created pretty simple generator and use
GWT.create to instantiate a class. I am expecting GWT will provide class
generated by my generator and it works as expected in dev mode. When I am
trying to make same in production, for some reason GWT does not provide
generated version. I have no idea what is wrong, maybe somebody have any
ideas? Thanks in advance!
*Class, modified by generator*
public class GeneratedInterface {
public String getValue(){
return null;
}
}
*Generator*
public String generate(TreeLogger logger, GeneratorContext ctx, String
requestedClass) throws UnableToCompleteException {
JClassType type = ctx.getTypeOracle().findType(requestedClass);
String packageName = type.getPackage().getName();
String simpleName = type.getSimpleSourceName() + "_Generated";
logger.log(TreeLogger.Type.INFO, "Create adapter " + packageName + "." +
simpleName + " for " + type.getQualifiedSourceName());
ClassSourceFileComposerFactory composer = new
ClassSourceFileComposerFactory(packageName, simpleName);
composer.setSuperclass(GeneratedInterface.class.getName());
PrintWriter printWriter = ctx.tryCreate(logger, packageName, simpleName);
String className = null;
if (printWriter != null) {
SourceWriter writer = composer.createSourceWriter(ctx, printWriter);
writer.println("public String getValue() {");
writer.println(" return \"Test interface\";");
writer.println("}");
writer.commit(logger);
className = composer.getCreatedClassName();
}
return className;
}
*EntryPoint*
public class GeneratorTest implements EntryPoint {
public void onModuleLoad() {
GeneratedInterface intf = GWT.create(GeneratedInterface.class);
log.info("deferred binding: " + intf.getClass().getName());
log.info("Value = " + intf.getValue());
}
}
*module.xml*
<generate-with class="com.xxx.xxx.gwt.generator.server.TestGenerator">
<when-type-assignable
class="com.xxx.xxx.gwt.generator.client.GeneratedInterface"/>
</generate-with>
As you can see, generator just provides implementation for
GeneratedInterface.getValue()
In case of dev mode, in logs I GWT uses generated class

In case of production mode, in logs I GWT does not use generated class
