* @class Ext.util.TaskRunner
* Provides the ability to execute one or more arbitrary tasks in a multithreaded
* manner. Generally, you can use the singleton {@link Ext.TaskMgr} instead, but
* if needed, you can create separate instances of TaskRunner. Any number of
* separate tasks can be started at any time and will run independently of each
* other. Example usage:
* <pre><code>
// Start a simple clock task that updates a div once per second
var updateClock = function(){
Ext.fly('clock').update(new Date().format('g:i:s A'));
}
var task = {
run: updateClock,
interval: 1000 //1 second
}
var runner = new Ext.util.TaskRunner();
runner.start(task);
// equivalent using TaskMgr
Ext.TaskMgr.start({
run: updateClock,
interval: 1000
});
* </code></pre>
* Also see {@link Ext.util.DelayedTask}.
