Provides the ability to execute one or more arbitrary tasks in a multithreaded -manner. Generally, you can use the singleton Ext.TaskManager 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:
- -// 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 TaskManager
-Ext.TaskManager.start({
- run: updateClock,
- interval: 1000
-});

-See the start method for details about how to configure a task object.
- - -Also see Ext.util.DelayedTask.

(optional) The minimum precision in milliseconds supported by this TaskRunner instance -(defaults to 10)
-Starts a new task.
-Starts a new task.
-A config object that supports the following properties:
run : FunctionThe function to execute each time the task is invoked. The
-function will be called at each interval and passed the args argument if specified, and the
-current invocation count if not.
If a particular scope (this reference) is required, be sure to specify it using the scope argument.
Return false from this function to terminate the task.
interval : Numberargs : Arrayrun. If not specified, the current invocation count is passed.scope : Objectrun function. Defaults to the task config object.duration : Numberrepeat : NumberBefore each invocation, Ext injects the property taskRunCount into the task object so
-that calculations based on the repeat count can be performed.
