AsynchronousTaskObject
AsynchronousTaskObject["name",id,sessionid]
is an object that represents asynchronous evaluations from a particular asynchronous task.
Details
- URLFetchAsynchronous returns an AsynchronousTaskObject.
- id is a serial number used to distinguish asynchronous tasks.
- sessionid is the $SessionID of the Wolfram System session where the AsynchronousTaskObject was created.
- An AsynchronousTaskObject can be passed to StopAsynchronousTask, StartAsynchronousTask, and WaitAsynchronousTask.
Examples
Basic Examples (1)
task1 = URLFetchAsynchronous["http://exampledata.wolfram.com/20mb.dat",
If[#2 === "data", MessageDialog["Download #1 complete."]]&]
task2 = URLFetchAsynchronous["http://exampledata.wolfram.com/20mb.dat",
If[#2 === "data", MessageDialog["Download #2 complete."]]&]Remove one of the download tasks using its AsynchronousTaskObject expression:
RemoveAsynchronousTask[task1]The removed task will no longer be listed:
