Project description
DojoX Timing is a project that deals with any kind of advanced use of timing
constructs. The central object, 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.
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.
dojo.doLater() provides a simple mechanism that checks a conditional before allowing
your function to continue. If the conditional is false, the function is blocked and continually
re-called, with arguments, until the conditional passes.
