Class RegexSplitter

  • All Implemented Interfaces:
    ChangeTable.Splitter

    public class RegexSplitter
    extends java.lang.Object
    implements ChangeTable.Splitter

    A ValueChanger.Splitter that splits a line of text using a regular expression, returning one value per match.

    A list of values is generated by effectively executing:

     matcher = pattern.matcher(value.toString());
    
     while(matcher.find()) {
       values.add(matcher.group(matchGroup);
     }
