Thomas,
Here is our client setup code for the pipes:
transport = new QosRequestTransport();
QosManager manager = new QosManager();
QosQueue root = new QosQueue();
root.setTarget(manager);
final QosQueue primary = injector.getDefaultPipe();
primary.setTarget(root);
// pipe we don't bug the user about
QosQueue background = injector.getBackgroundPipe();
background.setTarget(root);
background.addModifier(new Priority(0.5f));
final BusyDisplay busyDisplay =
UasInjector.INSTANCE.getBusyDisplay();
manager.addListener(new QosListener() {
@Override
public void tick(List<QosEntry> list) {
boolean block = false;
for (QosEntry entry : list) {
if (entry.getScore() >= 1.0f) {
block = true;
break;
}
}
if (busyDisplay.isShowing()) {
if (!block) {
busyDisplay.hide();
}
} else {
if (block) {
busyDisplay.show();
}
}
}
@Override
public void retryStarting(int retryCount) {
busyDisplay.setMessage("Possible network problem. Retry " +
retryCount + "...");
}
});
manager.start();
transport.setDefaultSource(primary);
NB if you fire a RequestContext in the normal way it gets captured by the
QosManager... Really ugly code relying on the single threaded nature of JS.
Might ask for more hooks from the core GWT/RequestFactory.
btw This is definitely meant to be sugar on top of an amazingly good
framework.
Cheers
Sam
