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, which implies it is memory
 fed. That's not a problem for all but the biggest properties files on contemporary hardware.
