DojoX Timing is a project that deals with any kind of advanced use of timing constructs.

dojox.timing.Timer

The central object of dojox.timing is dojox.timing.Timer (included by default), is a simple object that fires a callback on each tick of the timer, as well as when starting or stopping it. The interval of each tick is settable, but the default is 1 second--useful for driving something such as a clock.

dojo.require('dojox.timing');
t = new dojox.timing.Timer(1000);
t.onTick = function(){
 console.info("One second elapsed");
}
t.onStart = function(){
 console.info("Starting timer");
}
t.start();

Other elements

dojox.timing.Streamer is an object designed to facilitate streaming/buffer-type scenarios; it takes an input and an output function, will execute the output function onTick, and run the input function when the internal buffer gets beneath a certain threshold of items. This can be useful for something timed-- such as updating a data plot at every N interval, and getting new data from a source when there's less than X data points in the internal buffer (think real-time data updating).

dojox.timing.Sequencer is an object, similar to Streamer, that will allow you to set up a set of functions to be executed in a specific order, at specific intervals.

The DojoX Timing ThreadPool is a port from the original implementation in the f(m) library. It allows a user to feed a set of callback functions (wrapped in a Thread constructor) to a pool for background processing.
