1 00:00:00,660 --> 00:00:01,720 Hello, welcome back. 2 00:00:01,740 --> 00:00:07,020 In this lesson, we're going to see how to suspend a task, so I'm going to make a copy of this last 3 00:00:07,020 --> 00:00:07,560 project. 4 00:00:08,570 --> 00:00:17,120 Copy and then paste over here, and then I'm going to call this number eight, suspending the task. 5 00:00:27,750 --> 00:00:28,710 And I'm going to open it. 6 00:00:36,810 --> 00:00:37,290 OK. 7 00:00:38,310 --> 00:00:40,150 So let's get started. 8 00:00:40,620 --> 00:00:46,440 We're going to start off by having all of the tasks created with the same priority level, so I'm going 9 00:00:46,440 --> 00:00:51,780 to change the priority of blue over here to one such that they all have the same priority. 10 00:00:52,320 --> 00:00:56,050 And then over here we did get priority. 11 00:00:56,070 --> 00:00:56,970 I'm going to delete this. 12 00:00:56,970 --> 00:00:58,280 We don't need this for this project. 13 00:00:58,290 --> 00:01:00,000 We need such priority of blue. 14 00:01:00,020 --> 00:01:00,930 I'm going to delete this. 15 00:01:01,260 --> 00:01:04,830 So it looks like our task creation version. 16 00:01:05,610 --> 00:01:07,050 We've created three tasks. 17 00:01:07,260 --> 00:01:09,030 They all have priority of one. 18 00:01:09,390 --> 00:01:11,120 And here are the task functions. 19 00:01:11,520 --> 00:01:13,560 What I'm going to do is I'm going to make. 20 00:01:15,100 --> 00:01:16,030 I'm going to make. 21 00:01:17,220 --> 00:01:26,190 The red task suspend the blue task after a number of iterations and when I put a counter variable here 22 00:01:27,210 --> 00:01:34,530 over here of great, you ain't 32 unaskable to which I shall call to suspend, which, of course, suspend, 23 00:01:34,530 --> 00:01:41,090 monitor and assure the account that they would monitor when we should suspend just to demonstrate how 24 00:01:41,100 --> 00:01:42,120 suspension works. 25 00:01:42,690 --> 00:01:43,680 So come over here. 26 00:01:46,010 --> 00:01:53,090 What I'm going to do is I'm going to add a bit of delay to each of our profilers, otherwise this is 27 00:01:53,090 --> 00:01:56,060 just going to move very fast. 28 00:01:56,930 --> 00:01:59,600 So I'll create a local rainbow over here. 29 00:02:00,720 --> 00:02:07,160 Then I'll say four equals zero is less than. 30 00:02:08,770 --> 00:02:17,190 Let's see, a hundred thousand I plus plus, okay, I'm going to do the same for the others. 31 00:02:20,130 --> 00:02:23,430 Over here as well, then I'll copy this. 32 00:02:25,940 --> 00:02:28,690 Then over here, the local is yeah. 33 00:02:29,170 --> 00:02:30,630 OK, so here we are. 34 00:02:32,730 --> 00:02:36,900 What I'm going to do is, like we said in red, we're going to suspend. 35 00:02:37,970 --> 00:02:38,960 We're going to suspend. 36 00:02:41,950 --> 00:02:47,550 We're going to suspend Lisa Bloom, so whenever Red executes, I'm going to incrementalists or spend 37 00:02:47,570 --> 00:02:49,330 money to assess or spend money to. 38 00:02:49,360 --> 00:02:50,080 Plus, plus. 39 00:02:50,950 --> 00:02:51,440 Okay. 40 00:02:52,240 --> 00:02:57,990 And then I'm going to see if suspend monitor. 41 00:02:59,980 --> 00:03:01,020 It's just been monitored. 42 00:03:01,030 --> 00:03:03,460 Alesi is greater than. 43 00:03:05,200 --> 00:03:11,890 Or equal to 50, then we would we would invoke a piece of code. 44 00:03:14,880 --> 00:03:19,080 Or invoke this function v task, suspend. 45 00:03:19,110 --> 00:03:21,960 This is the function for suspending the task. 46 00:03:22,500 --> 00:03:25,240 All we have to do is pass the task function here. 47 00:03:26,310 --> 00:03:29,100 The task Hondo sorry, arguments. 48 00:03:31,690 --> 00:03:34,880 OK, so let's see how that works. 49 00:03:35,350 --> 00:03:42,850 The reason I'm using suspend Monitise, if we simply call V task suspend, then we would see that before 50 00:03:42,850 --> 00:03:44,540 and after suspension changes. 51 00:03:44,860 --> 00:03:51,550 So what we would see is actually we would see that all task will be running and then after a while would 52 00:03:51,550 --> 00:03:52,220 stop running. 53 00:03:52,740 --> 00:03:54,580 OK, I'll click here to view it. 54 00:03:59,260 --> 00:03:59,810 Luca. 55 00:04:01,610 --> 00:04:04,640 There's so little money here to build. 56 00:04:07,620 --> 00:04:08,740 People successfully. 57 00:04:09,810 --> 00:04:11,220 Quickly, let's get onto the board. 58 00:04:12,870 --> 00:04:13,530 But eight. 59 00:04:15,380 --> 00:04:16,030 OK. 60 00:04:21,090 --> 00:04:21,480 Which. 61 00:04:23,240 --> 00:04:24,970 So I'm going to come over here. 62 00:04:27,170 --> 00:04:32,790 And I'm going to spend money to watch winter, where I spend money to controversy. 63 00:04:34,570 --> 00:04:43,600 Ed, over here, then I'm going to click to run or iterate and suspend monitors currently 17, 18, 64 00:04:43,600 --> 00:04:44,170 19. 65 00:04:44,440 --> 00:04:46,810 I see, I see they're all going. 66 00:04:48,030 --> 00:04:50,560 They are all iterates, and that's almost the same rate. 67 00:04:51,730 --> 00:05:00,280 OK, you see where I spend money to pass 50 blue stopped moving, now we just have red and green moving. 68 00:05:00,490 --> 00:05:03,650 So blue has been suspended, right? 69 00:05:04,000 --> 00:05:05,620 So that is how we suspend a task. 70 00:05:06,250 --> 00:05:07,410 So we suspend the task. 71 00:05:07,900 --> 00:05:08,270 Right. 72 00:05:09,160 --> 00:05:15,790 So I'm going to create another project or what I'm going to do is actually I'll leave this to you as 73 00:05:15,820 --> 00:05:16,500 assignment. 74 00:05:17,020 --> 00:05:24,520 So I, I want you to create a function or create a project in which the task suspends itself. 75 00:05:25,940 --> 00:05:32,540 Remember, we saw that we said if you want to suspend a task, if you undertook the task to suspend 76 00:05:32,540 --> 00:05:37,180 itself, you can either pass now or the task Hondo as the argument. 77 00:05:37,730 --> 00:05:44,900 So I want you to to run the experiment and make sure it works just like we saw for the set priority 78 00:05:44,900 --> 00:05:45,390 function. 79 00:05:45,950 --> 00:05:46,430 OK. 80 00:05:48,020 --> 00:05:48,440 Right. 81 00:05:49,040 --> 00:05:55,550 So in the next lesson, we're going to see how to resume the task, we've seen how to suspend a task 82 00:05:55,550 --> 00:05:58,870 here, we would have to find ways to resume them when we suspend him. 83 00:05:59,390 --> 00:06:01,460 So I'll see you in the next lesson of a nice.
