Asynchronous means that you trigger an event to be completed some time in the future. There are two variations in GWT: asynchronous RPC calls to the server, and timers/scheduled commands. RPC calls send a request to the server, then at some later point, the server responds and triggers a callback. Timers/Scheduled Commands (see Scheduler) specify a method to run after some timeout. However, keep in mind that JavaScript is single threaded. Lets say you schedule a Timer for 1ms, then synchronously perform 100ms worth of code execution. Since JavaScript is single threaded, your Timer will not fire for at least 100ms, even though you scheduled it for 1ms. Its asynchronous because the code in the Timer executes after the current execution block. > > > > > > -- > > You received this message because you are subscribed to the Google Groups > "Google Web Toolkit" group. > > To post to this group, send email to google-web-toolkit@googlegroups.com > . > > To unsubscribe from this group, send email to > google-web-toolkit+unsubscr...@googlegroups.com<google-web-toolkit%2bunsubscr...@googlegroups.com> > . > > For more options, visit this group at > http://groups.google.com/group/google-web-toolkit?hl=en. > > > > > > > > -- > David Chandler > Developer Programs Engineer, Google Web Toolkit > http://googlewebtoolkit.blogspot.com/ > > -- > You received this message because you are subscribed to the Google Groups > "Google Web Toolkit" group. > To post to this group, send email to google-web-tool...@googlegroups.com. > To unsubscribe from this group, send email to > google-web-toolkit+unsubscr...@googlegroups.com<google-web-toolkit%2bunsubscr...@googlegroups.com> > . > For more options, visit this group at > http://groups.google.com/group/google-web-toolkit?hl=en. > > -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
