求大佬告知如何设置Task优先级

 
@Concurrent 
function printArgs(args: number): number { 
  console.log("printArgs: " + args); 
  return args; 
} 
 
let task: taskpool.Task = new taskpool.Task(printArgs, 100); // 100: test number 
taskpool.execute(task, taskpool.Priority.HIGH).then((res) => { 
  console.log("taskpool result is :" + res); 
});
