00:00:11,610 --> 00:00:16,950
Hello and welcome to the Gold Anchor Academy language course in the previous session.

2
00:00:17,400 --> 00:00:23,940
We could define create IP function, and in this session we want to create another function.

3
00:00:24,960 --> 00:00:29,610
The main metal in the client should be contains two functions.

4
00:00:30,240 --> 00:00:36,510
First, the function for receiving message and second, the function for sending a message.

5
00:00:37,740 --> 00:00:46,140
Now we go to implement the receive message function for do this create a new function name like receive

6
00:00:46,140 --> 00:00:46,710
message.

7
00:00:47,010 --> 00:00:50,550
So we right fine.

8
00:00:54,530 --> 00:00:55,430
Receive

9
00:00:58,550 --> 00:00:59,300
message.

10
00:01:03,670 --> 00:01:10,450
This function, except it parameters, point of VIPs to get connection, so set the variable light connection

11
00:01:12,790 --> 00:01:16,330
by the time point of that circuit connection.

12
00:01:20,340 --> 00:01:21,380
That connects.

13
00:01:25,490 --> 00:01:31,730
We use infinite loop, therefore our function is always ready to receive the message.

14
00:01:32,240 --> 00:01:34,010
So right for

15
00:01:37,280 --> 00:01:45,350
now, given to receive a message from client to do these views from Jason Cadec, Jason is a codec to

16
00:01:45,350 --> 00:01:49,790
send or receive JSON data in a frame from events to get the conviction.

17
00:01:50,600 --> 00:01:57,860
So from that, to get package calling Jason and invoking receive method, this method returns and it

18
00:01:57,860 --> 00:02:02,680
also defined invariant and like of a roll calling equals.

19
00:02:03,640 --> 00:02:04,550
We have two kids.

20
00:02:08,840 --> 00:02:09,590
Jason?

21
00:02:13,230 --> 00:02:19,200
Dont receive this method, accept two parameters.

22
00:02:19,500 --> 00:02:22,830
First, the clinics in Seoul visit connection.

23
00:02:26,410 --> 00:02:34,000
And another object is needed, a second parameter to be able to put the received data inside it after

24
00:02:34,000 --> 00:02:34,990
the serializing.

25
00:02:35,410 --> 00:02:38,410
So we are using in messages to object here.

26
00:02:38,470 --> 00:02:44,500
Therefore, first define an object from messages throughout and pass it as pointer the function.

27
00:02:45,730 --> 00:02:58,450
So define a variable like VAR message from messages that I've could package that message.

28
00:03:01,360 --> 00:03:07,000
And set this very in a second argument for reserve function.

29
00:03:09,380 --> 00:03:18,730
OK, now implements erode status, if at all not equals, Neal.

30
00:03:19,520 --> 00:03:38,600
Lock the Fattore and set the message at all and receive state talent and said, I don't message if there

31
00:03:38,600 --> 00:03:39,320
is an error.

32
00:03:39,350 --> 00:03:42,980
The program should not be stopped and should continue to work.

33
00:03:42,990 --> 00:03:48,200
So use continue command and go to the next line and continue.

34
00:03:51,310 --> 00:03:58,030
And if there is no, it will print the message, so be right, if the

35
00:04:01,690 --> 00:04:13,000
message is and said message got subject.

36
00:04:14,390 --> 00:04:18,320
We were able to implement the receive message function.

37
00:04:19,160 --> 00:04:24,980
Now we can the created function inside the main method as a separate go routine.

38
00:04:25,160 --> 00:04:27,290
So go to main function.

39
00:04:32,380 --> 00:04:41,020
And calling receive message as a good routine, but before you check every state, if they're not equals

40
00:04:41,020 --> 00:04:46,990
mean, the log dots fatal error dot at all.

41
00:04:47,590 --> 00:04:56,980
And now receive my state as the gold routine go routine receive message and that connection as argument

42
00:04:56,980 --> 00:04:58,740
for connection.

43
00:04:59,530 --> 00:05:05,200
So top of calling this off message function to make sure our connection is closed after this event is

44
00:05:05,200 --> 00:05:05,530
done.

45
00:05:05,530 --> 00:05:08,800
A close connection by the common deeper connection close.

46
00:05:11,160 --> 00:05:16,860
So, right, defer connection that close.

47
00:05:18,300 --> 00:05:25,800
Now we go to implement the send message for do these create a new function named like send message?

48
00:05:26,130 --> 00:05:38,070
So go after to receive message promotion and create another function like fine send message.

49
00:05:40,590 --> 00:05:44,340
This function, I accept the parameterized Paul introverts to get the connection.

50
00:05:44,970 --> 00:05:52,560
So set a variable like connection by the time point of that connection.

51
00:05:59,200 --> 00:05:59,500
OK.

52
00:06:01,720 --> 00:06:08,740
To get the value from the standard input we use, the newest cannot function from both I or package

53
00:06:09,760 --> 00:06:11,350
and create a scanner.

54
00:06:11,710 --> 00:06:15,280
This function returns and munis cannot read from a reader.

55
00:06:15,310 --> 00:06:28,780
So first, define a variable like a scanner scanner column e calls from both or package calling new

56
00:06:28,790 --> 00:06:31,090
scanner function new scanner.

57
00:06:33,190 --> 00:06:42,070
Set a standard input from always packaged as argument for the sponsor if the event is open fires pointing

58
00:06:42,070 --> 00:06:43,820
to the standard input.

59
00:06:43,870 --> 00:06:51,940
So the right OS got tested, I had to retain information in this scanner.

60
00:06:52,180 --> 00:07:00,430
We need a for loop and this volume is activated when the user has sent information via input a standard,

61
00:07:00,640 --> 00:07:04,060
and we do this by invoking the scan function.

62
00:07:04,810 --> 00:07:06,790
So go to the next line.

63
00:07:10,530 --> 00:07:12,780
Full scanner

64
00:07:15,810 --> 00:07:17,790
calling a scan function.

65
00:07:22,380 --> 00:07:29,820
If the user enters information inside based on their input, the program infers the full loop and this

66
00:07:29,820 --> 00:07:37,170
can function is called and reads the information in the scanner and we get it scanner data by calling

67
00:07:37,200 --> 00:07:38,250
text function.

68
00:07:38,490 --> 00:07:41,100
So first, define the value of a like text

69
00:07:43,980 --> 00:07:45,040
text column.

70
00:07:45,190 --> 00:07:50,820
He equals scanner dart text.

71
00:07:54,010 --> 00:08:00,070
Now we send the receive data inside that takes very able to the server via adjacent formats.

72
00:08:00,580 --> 00:08:10,150
We do this by calling Send Metal France wicket package sent metal access to parameters first the connection.

73
00:08:10,180 --> 00:08:11,680
Second is an object.

74
00:08:12,190 --> 00:08:16,360
In this case, our argument is an object from messages struct.

75
00:08:17,050 --> 00:08:23,110
So before cutting send function, we create the message variable and initialize the subject field of

76
00:08:23,110 --> 00:08:26,020
message is struck by the text field value.

77
00:08:26,230 --> 00:08:28,960
So we write message.

78
00:08:32,900 --> 00:08:35,060
Calling equal socket.

79
00:08:37,060 --> 00:08:38,470
Dot mrJ

80
00:08:41,470 --> 00:08:46,230
and initialise subject by text Lalibela.

81
00:08:48,610 --> 00:08:52,990
Oh, here we named Test, we changed it to text.

82
00:08:54,890 --> 00:09:04,280
OK, now calling same function, this function returns and enter object, so we define an error value

83
00:09:04,420 --> 00:09:11,890
in error column equals left sutured dot jason

84
00:09:14,380 --> 00:09:26,470
dot 7th function and sip connection as a first argument connection and sip message a second argument

85
00:09:27,610 --> 00:09:28,330
message.

86
00:09:30,130 --> 00:09:30,970
Now check it out.

87
00:09:30,980 --> 00:09:36,910
A status, if add or not, means display on the roof.

88
00:09:37,110 --> 00:09:37,780
If be.

89
00:09:41,040 --> 00:09:48,570
Error in send data and set error valid

90
00:09:51,630 --> 00:09:56,130
if there is an error, the program should not be stopped and should continue to work.

91
00:09:56,140 --> 00:10:01,320
So use continue command, go to the next line and continue.

92
00:10:04,470 --> 00:10:04,800
OK.

93
00:10:06,180 --> 00:10:09,900
We were able to implement the decent message function.

94
00:10:10,110 --> 00:10:13,770
Now we called the created function inside the main metal.

95
00:10:14,490 --> 00:10:16,260
So go to main method.

96
00:10:19,160 --> 00:10:28,990
And right, the function send a message and that connection is argument for it.

97
00:10:31,430 --> 00:10:34,070
Before that, they called Save the Project.

98
00:10:34,880 --> 00:10:41,870
In this case, we could implement the client line in order not to prolong the time of decision.

99
00:10:41,990 --> 00:10:46,100
We will finish it and we will continue the content in the next session.

100
00:10:46,250 --> 00:10:46,810
Goodbye.
