how to copy iostream& data into string?

[hanna88]

hello,
im having problem to copy the data from iostream& into string.and im not sure am i doing the right way by using getline.can anyone give hints how to solve this.

here's to make things clear:

 
//method that reads through the stream and breaks it into words and sentence
 
Document*Repository::addDoc(iostream& inStream,string docId)
 
//test core
 
Repository r1;
stringstream ss;
 
string s1 = "Hello World;"
 
ss.clear();
ss<<s1;
r1.addDoc(ss,"1")
 
 
 

thanks in advance

That code snippet does access iostream& and doesn't copy into a string.

It copies a string into a streamstream which looks ok to me.

thanks for your reply.

@Banfa
so how can i access the copied string into streamstream should i convert it back to string in order to use string method like strtok?

If you mean should you convert it into a C string to use strtok then no. strtok is an evil function and should be avoided.

However you could convert it back into a string (the C++ variety) and use the member functions of string (find and substr) to tokenise it.

the string is been passed in iostream& form and the only for me to get access on the string is getline().im not sure whether it is right by using getline() first then convert it into string in order to tokenize it.

any hint would be great! thanks again

You don't need to use getline then convert it to a string, getline can read straight into a string

string getline reference

Even so conversion to a string is still better than calling strtok.
