Class Replacer

  • public class Replacer
extends java.lang.Object
    The Replacer class suggests some methods to replace occurences of a pattern either by a result of evaluation of a perl-like expression, or by a plain string, or according to a custom substitution model, provided as a Substitution interface implementation.
    A Replacer instance may be obtained either using Pattern.replacer(...) method, or by constructor:
     Pattern p=new Pattern("\\w+");
 Replacer perlExpressionReplacer=p.replacer("[$&]");
 //or another way to do the same
 Substitution myOwnModel=new Substitution(){
    public void appendSubstitution(MatchResult match,TextBuffer tb){
       tb.append('[');
       match.getGroup(MatchResult.MATCH,tb);
       tb.append(']');
    }
 }
 Replacer myVeryOwnReplacer=new Replacer(p,myOwnModel);
    The second method is much more verbose, but gives more freedom. To perform a replacement call replace(someInput):
     System.out.print(perlExpressionReplacer.replace("All your base "));
 System.out.println(myVeryOwnReplacer.replace("are belong to us"));
 //result: "[All] [your] [base] [are] [belong] [to] [us]"
