Timers example

This sample consist in a command line demonstrating the use of the TIMER (Timer) class to generate a periodic callback to a method. The sample creates a TIMER object and passes to it a delegate object. When the TIMER fires, the delegate is invoked, and a static method is called asynchronously by a worker thread in the thread pool.

When the display is finished, the application wait for you to pressed the return key to finished the application.

Under the Hood

This application shows how to use the thread TIMER. The timer is launched (create my_timer.make_with_callback (create {TIMER_CALLBACK}.make (Current, $check_status), Void, 0, 2000)) and call the feature check_status that displays the message "Checking Status." every two seconds.

This sample contains the following class:

• TIMER
• TIMER_CALLBACK
