Class Replacer

java.lang.Object
  org.javasimon.utils.Replacer

public final class Replacer
extends Object

Replacer stores from regex as pattern and its process(java.lang.String) method than returns string with all from replaced with to. Using the replacer should be faster because the regex is compiled only once. Pattern.matcher(CharSequence) and Matcher.replaceAll(String) is used internally, hence to parameter is regex as well and can reference matched group from the from String.

Behavior can be further modified by Replacer.Modificators.
