util.regex

The regex package contains additional classes which work with the Java regex package.

RegexCollection

The RegexCollection class allows to specify a list of regex patterns and match a CharSequence against all the patterns. It simplifies the usage of several regex expressions against the same input.

Example

The following example shows a simple usage of the class:

   RegexCollection collection = new RegexCollection();
   collection.addPattern("number", "\\d+");
   collection.addPattern("letters", "[A-Za-z]+");
      
   RegexMatcher matcher = collection.matcher("156");
   String name = matcher.getPatternName(); // return "number"
   boolean matches = matcher.matches(); // return true

   matcher = collection.matcher("Slayer");
   name = matcher.getPatternName(); // return "letters"
   matches = matcher.matches(); // return true

   matcher = collection.matcher("1349 band");
   name = matcher.getPatternName(); // return "letters"
   matches = matcher.matches(); // return false
