Dear all,
I am new to boost and tried to use the Tokenizer lib. But I have a
problem. When I initialize a tokenizer object in a loop and tokenize
that, it is ok on the first iteration. But on the second and subsequent
iterations, even if I try to initialize the object with some different
string, the object always tokenizes the first initialization. So I see
that I have to reset the tokenizer object at each iteration. But I could
not understand how to do this from the tokenizer man pages.
Here is some code :
// define tokenizer and separator
typedef boost::tokenizer tokenizer;
boost::char_separator<char> sep(" = ");
..
.
.
//initialize and use in a loop
while(getline(inFile,readLine)){
//skip empty lines for count operation
if(!readLine.empty()){
// each line is tokenized
tokenizer tokens(readLine, sep);
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!<======
// tokens are pushed on a vector
for (tokenizer::iterator tok_iter = tokens.begin();
tok_iter != tokens.end(); ++tok_iter)
lineTokens.push_back(*tok_iter);
// lineTokens hold the tokens
// check if the configuration file is valid by the count
// function of the set
if(configVars.count(lineTokens[0])==1){ // means existent so
this is valid
// assign the read value to the right class data member
switch(line_count){
// switch can be extended depending on the configuration file
// decide on the line number of the configuration file
case 0:// line 1
vlInputFileName=lineTokens[1];
break;
case 1:// line 2
vlProjectFileName=lineTokens[1];
break;
case 2:// line 3
vlcatvbsFileName=lineTokens[1];
break;
case 3:// line 4
vlVbModuleName=lineTokens[1];
break;
case 4:// line 5
pathToVLProjectFile=lineTokens[1];
break;
// case lines can be added here
// ...
default:
;
break;
}
}
else
throw std::runtime_error("The configuration file variable(s)
are not valid!");
// clear the line for the next operation
readLine.clear();
line_count+=1;
// I should reset tokenizer object but I could not do
<========================= Reset tokenizer after each iteration
Your help is very much appreciated
Best regards,
Umut
