stringTokenizer

[Ganon11]

Hey,

Last year I was working in Java, and one of the predefined classes we used was the stringTokenizer.java class. I wanted to use this in C++, but couldn't find a predefined class. So I made my own class - here's the code:

#include <iostream>
#include <string>
using namespace std;
 
class stringTokenizer {
      public:
             void setMessage(string newMessage);
             string next();
             bool hasNext();
             stringTokenizer(string myMes, char myCh, bool retDel);
             stringTokenizer(string myMes, char myCh);
             stringTokenizer(string myMes);
 
      private:
              void processBlanks();
              string message;
              char ch;
              bool delRet;
};
 
stringTokenizer::stringTokenizer(string myMes, char myCh, bool retDel) {
    message = myMes;
    ch = myCh;
    delRet = retDel;
}
 
stringTokenizer::stringTokenizer(string myMes, char myCh) {
    message = myMes;
    ch = myCh;
    delRet = false;
}
 
stringTokenizer::stringTokenizer(string myMes) {
    message = myMes;
    ch = ' ';
    delRet = false;
}
 
void stringTokenizer::setMessage(string newMessage) {
     message = newMessage;
}
 
string stringTokenizer::next() {
    string word;
    if (!delRet) {
        processBlanks();
        int pos = message.find(ch);
        if (pos != string::npos) {
            word = message.substr(0, pos);
            message = message.substr(pos);
        } else {
            word = message;
            message = "";
        }
    } else {
        if (message[0] == ch) {
            word = message.substr(0, 1);
            message = message.substr(1);
        } else {
            int pos = message.find(ch);
            if (pos != string::npos) {
                word = message.substr(0, pos);
                message = message.substr(pos);
            } else {
                word = message;
                message = "";
            }
        }
    }
    return word;
}
 
bool stringTokenizer::hasNext() {
     return message.length() > 0;
}
 
void stringTokenizer::processBlanks() {
     while (message.length() > 0 && message[0] == ch)
           message = message.substr(1);
     return;
}

My question is, for any Java/C++ users out there, is there anything I can improve to make this as identical as possible in implementation as the Java class? I have looked at the Java summary of the stringTokenizer class at http://java.sun.com/j2se/1.4.2/docs/api/java/util/StringTokenizer.html

Thanks for any help.

u can check this website which gives information about string tokenizers in c++

hope its of some use,

thank you,
