Method Detail

• getANTLRCharLiteralForChar

  public static String getANTLRCharLiteralForChar(int c)

  Return a string representing the escaped char for code c. E.g., If c has value 0x100, you will get "Ā". ASCII gets the usual char (non-hex) representation. Control characters are spit out as unicode. While this is specially set up for returning Java strings, it can be used by any language target that has the same syntax. :)

• getCharValueFromGrammarCharLiteral

  public static int getCharValueFromGrammarCharLiteral(String literal)

  Given a literal like (the 3 char sequence with single quotes) 'a', return the int value of 'a'. Convert escape sequences here also. Return -1 if not single char.

• getCharValueFromCharInGrammarLiteral

  public static int getCharValueFromCharInGrammarLiteral(String cstr)

  Given char x or \t or ሴ return the char value; Unnecessary escapes like '\{' yield -1.

• getStringFromGrammarStringLiteral

  public static String getStringFromGrammarStringLiteral(String literal)

• capitalize

  public static String capitalize(String s)
