They are Singletons.
Check this snippet from Server. The Server singleton has the reference to the
sender and receiver singletons. We pass the references via loadApp(). Does this
make sense?
/* After some indirection we get the injector. */
injector = Guice.createInjector(module);
Sender sender = injector.getInstance(Sender.class);
Receiver receiver = injector.getInstance(Receiver.class);
// File[] s4rFiles = new File(appsDir).listFiles(new
PatternFilenameFilter("\\w+\\.s4r"));
File[] s4rFiles = new File(appsDir).listFiles(new
PatternFilenameFilter(".+.s4r"));
for (File s4rFile : s4rFiles) {
logger.info("Loading app: " + s4rFile.getPath());
loadApp(sender, receiver, s4rFile);
}
/* Now init + start apps. TODO: implement dynamic loading/unloading
using ZK. */
for (App app : apps) {
logger.info("Starting app " + app.getClass().getName());
app.init();
app.start();
}
