I am looking for an elegant way to synchronize objects between multiple clients and a server over the web.
1. Client A registers for notifications of changes to a object O with the server S.
2. Client B notifies the server S that it has modified a property of the object O.
3. Server S checks which clients registered for updates to the object O, identified Client A and notifies the client A of a change.
4. Client A updates the local instance of object O.
5. Object O on the client A and object O on the client B are not synchronized.
Question: does Google Web Toolbox offers an out of the box solution to the architecture above?
Note: i know i can do this manually, with the Event Bus, for example. I am wondering if there is an out of the box solution that can let me simply register objects for updates and keep them synchronized without "reinventing the bicycle.."
This Micro Tutorial will demonstrate how nuggets on the Web are formatted by using Chrome Developer Tools. These tools would not only view the site's CSS but it can also modify it and save the CSS to use on your own site.
This Micro Tutorial will demonstrate how MozBar finds back links of any website you visit, as well as page, social shares to the page, and domain level metrics. There will me practical applications for this data.
