$AsynchronousTask

$AsynchronousTask is being phased out in favor of $CurrentTask, which was introduced experimentally in Version 11.2.

$AsynchronousTask

returns the current AsynchronousTaskObject.

Details

  • $AsynchronousTask is set when the Wolfram Language evaluates an asynchronous task's event function or error function.

Examples

Basic Examples  (2)

When the Wolfram Language evaluates the event function, $AsynchronousTask is set to the AsynchronousTaskObject that generated the event:

Wolfram Language code: URLFetchAsynchronous["http://exampledata.wolfram.com/5mb.dat", If[#2 === "data", MessageDialog[Column[{"Download complete for ", $AsynchronousTask}]]]&]

When not running an event function or error function, $AsynchronousTask is not set:
