I want to partition a QByteArray message efficiently, so this function I implemented take the Bytes, the part I want to extract, and toEnd flag which tells if I want to extract part1 till the end of the array. my dilimeter is spcae ' '
example if I have:
ba = "HELLO HOW ARE YOU?"
ba1 = getPart(ba, 1, false) -> ba1 = "HELLO"
ba2 = getPart(ba, 2, true) -> ba2 = "HOW ARE YOU?"
ba3 = getPart(ba, 3, false) -> ba3 = "ARE"
the function below works just fine, but I am wondering if this is efficient. should I consider using split function?
QByteArray Server::getPart(const QByteArray message, int part, bool toEnd)
{
QByteArray string;
int startsFrom = 0;
int endsAt = 0;
int count = 0;
for(int i = 0; i < message.size(); i++)
{
if(message.at(i) == ' ')
{
count++;
if(part == count)
{
endsAt = i;
break;
}
string.clear();
startsFrom = i + 1;
}
string.append(message.at(i));
}
if(toEnd)
{
for(int i = endsAt; i < message.size(); i++)
{
string.append(message.at(i));
}
}
return string;
}
