Class ConfigFileTokenizer

java.lang.Object
  gnu.javax.security.auth.login.ConfigFileTokenizer

public class ConfigFileTokenizer
extends java.lang.Object

A UTF-8 friendly, JAAS Login Module Configuration file tokenizer written in the deault syntax. This class emulates, to a certain extent, the behavior of a java.io.SrteamTokenizer instance st, when set as follows:

  st.resetSyntax();
  st.lowerCaseMode(false);
  st.slashSlashComments(true);
  st.slashStarComments(true);
  st.eolIsSignificant(false);
  st.wordChars('_', '_');
  st.wordChars('$', '$');
  st.wordChars('A', 'Z');
  st.wordChars('a', 'z');
  st.wordChars('0', '9');
  st.wordChars('.', '.');
  st.whitespaceChars(' ', ' ');
  st.whitespaceChars('\t', '\t');
  st.whitespaceChars('\f', '\f');
  st.whitespaceChars('\r', '\r');
  st.whitespaceChars('\n', '\n');
  st.quoteChar('"');
  st.quoteChar('\'');

The most important (negative) difference with a java.io.StreamTokenizer is that this tokenizer does not properly handle C++ and Java // style comments in the middle of the line. It only ignores them if/when found at the start of the line.
