The Future Object has the following functions:

  • cancel() returns Boolean
  • isCancelled() returns Boolean
  • isDone() returns Boolean
  • error() returns Future
  • get(closure, timezone) returns Future
  • then(closure, timezone) returns Future
RunAsync( closure=object, timeout=number );

Returns: object

Argument Description Default

Alias: callback, udf, function

Examples

future = runAsync(function(){
		return 10;
	}).then( function(input){
		return input + 20;
	});
	dump(future);
	result = future.get(10); // 10 is timeout(in ms)
	writeOutput(result); // output is 30
