Class PropertiesLexer

java.lang.Object
  asia.redact.bracket.properties.PropertiesLexer

public class PropertiesLexer
extends Object

Parse a properties file conforming to the description at http://download.oracle.com/javase/6/docs/api/java/util/Properties.html#load(java.io.Reader) into tokens. There is one additional extension: a comment line which starts with #;; is treated as transient (not read in). This is used later to generate a transient header and footer This is an "off-line" lexer, it is backed by a String as input
