Question

I m using the method quoteChar( " ) to treat the strings. The usual escape sequences such as " " and " " are recognized and converted to single characters as the string is parsed. Is there any way to get the string just the way it is, meaning that if i have the string:

Hello World

i 想要获得

Hello World

而不是:

Hello World

. Thanks

看看<条码>Stream Tokenizer来源,就象脚踏脚的越狱行为一样难以编码。我只能想出几个途径来绕过:

Re-escape the string once you get it back. The problem here is that this won t match exactly what was in the file - will be converted back but 40 will not.
Insert your own Reader in between the source Reader and the StreamTokenizer. Store all the chars read for the last token in a buffer. Trim whitespace from the start of that buffer to get the "raw" token.
If your tokenizing rules are simple enough, implement your own tokenizer.

这对我来说是有用的:

public class MyReader extends BufferedReader {
    // You can choose whatever replacement you d like(one wont occur in your text)
    private static final char TAB_REPLACEMENT =  u0000 ;

    public MyReader(Reader in) {
        super(in);
    }

    @Override
    public int read() throws IOException {
        int charVal = super.read();
        if (charVal ==  	 ) {
            return TAB_REPLACEMENT;
        }
        return charVal;
    }
}

and then create the tokenizer by:

myTokenizer = new StreamTokenizer(new MyReader(new FileReader(file)));

并且通过新的体积

MyTokenizer.sval.replace(TAB_REPLACEMENT,  	 )
