What is the GWT replacement for java.util.regex.Pattern.quote(String arg)

Question

In my app I need the code like:

string1.replaceAll(string2, myConstatntString)

Problem is that string1 and string2 can contain special symbols like '('.

I wish to quote string2 using java.util.regex.Pattern.quote(String arg):

string1.replaceAll(Pattern.quote(string2), myConstatntString);

But java.util.regex.Pattern is not available in GWT client side. Does GWT have any replacements for Pattern.quote?

Answer 1

I believe there isn't, because JavaScript doesn't have its own method. What you can do is to use String.replace() instead of String.replaceAll(), given that you don't need regexp at all. If you do, you will have to write your own method.

This is how it is done in JavaScript: Is there a RegExp.escape function in Javascript?

And this is how it is done in Java:

public static String quote(String s) {
    int slashEIndex = s.indexOf("\\E");
    if (slashEIndex == -1)
        return "\\Q" + s + "\\E";

    StringBuilder sb = new StringBuilder(s.length() * 2);
    sb.append("\\Q");
    slashEIndex = 0;
    int current = 0;
    while ((slashEIndex = s.indexOf("\\E", current)) != -1) {
        sb.append(s.substring(current, slashEIndex));
        current = slashEIndex + 2;
        sb.append("\\E\\\\E\\Q");
    }
    sb.append(s.substring(current, s.length()));
    sb.append("\\E");
    return sb.toString();
}
