How to split Array

[A Former User]

I am new for Qt C++. I am trying to receive a string from server which includes data.

I have tried with one String sending from server, received via websocket. I have stored that, then taken to another thread. Here I have posted my code, what I have done. I don't know whether that is correct or not.

Kindly assist me to get a solution for that.

websocket.cpp (I will receive the string from server, it contains data)

else if(message.contains("starting")) 
{
   startvalue = message;
   qDebug() << startvalue;
}

Received message from server

"start|value|10|5"

startval = EchoClient::startvalue;
QStringList value = startval.split("|");

So, I can easily split and assign the function.

For Example if I receive like this

"start|value|1|5" , "start|value|3|5" , "start|value|5|5" , "start|value|7|5" , "start|value|10|6"

I can split but how can I complete each task one by one ?

Task 1 : start|value|1|5
Task 2 : start|value|3|5
Task 3 : start|value|5|5
Task 4 : start|value|7|5
Task 5 : start|value|10|6

How can I use Array for this ? First I want to split each one then One by one I want to complete all task, it should not get interfere.

@Geeva Sorry, but I don't get what exactly the problem is?
"I can split but how can I complete each task one by one ?" - what do you mean? What is the problem?
Also shouldn't this be

else if(message.contains("starting"))

rather

else if(message.contains("start"))

?

Ya I have wrongly mentioned. It will be start only. What I have done.

This message I have received from server

"start|value|10|5"

Received message spitted using this

QStringList value = startval.split("|");

x = 10;
y = 5;

Now I can do whatever I want. I have tried that is working fine.

Here is the problem. If I receive like this

"start|value|1|5" , "start|value|3|5" , "start|value|5|5" , "start|value|7|5" , "start|value|10|6"

Everything have different task, lets say above 5 tasks

Task 1 : start|value|1|5
Task 2 : start|value|3|5
Task 3 : start|value|5|5
Task 4 : start|value|7|5
Task 5 : start|value|10|6

Question 1 : I think I can able to split similar I have tried with one task. Or else any other ways I want to use ?

Question 2 : After splitting now I have 5 tasks. I want to complete one by one. After completed first task then only I can use and complete 2nd task. How can I create those structure ? How can I use Array for that ? or else any other way ?

@Geeva array is a bit inflexible for your task here, as they, generally, have a fixed size.

I would suggest using a QList or an QVector

QList<QList<QString> > myList;
//or QVector<QVector<QString> > myVector

with Append you can add an other List. In your case here:

QList<QList<QString>> myList;

myList.append(startval.split("|"));

You access the list via the first indx of the list:

QStringList sl = myList.at(0);
QString s = myList.at(0).at(0);
//alternativly myList[0][0]

@J-Hilk Thanks for your response. I have tried QList for one task that is working fine, but how can I check with remaining task ?

It should complete the first task then only it should go for another task.

What I have done with first task.

startvalue = Server::Start;
qDebug() << "Value Received from server :" << startvalue;
QStringList first = startvalue.split("|");
int firstSize = first.size();
qDebug() << "size :" << firstSize;

if(firstSize == 5){
     first1 = first[2];
     first2 = first[3];
  }..........(continue)

From here I will check array size and split after that whatever the value I want I will take and use this is for one task.

For multiple task ? I don't have experience, kindly elaborate your answer.

@Geeva
The easies way is to move your task into its own function that expects q QList<QString> as an argument:

void myClass::myFunction(QList<QString> startvalue){
    //do stuff eg:
    qDebug() << "Value Received from server :" << startvalue;
    QStringList first = startvalue.split("|");
    int firstSize = first.size();
    qDebug() << "size :" << firstSize;

    if(firstSize == 5){
     first1 = first[2];
     first2 = first[3];
  }..........(continue)
}

then you call that function for each and every item in your QList<QList<QString>>

QList<QList<QString> > myList
for(QList<QString> ls : myList){
    myFunction(ls);
}
