Method Details
- skipWhiteSpace
  
  void skipWhiteSpace()
  
  Skip white space.
- nextChar
  
  int nextChar()
  
  returns the next character moving the file pointer or index to the next location.
- currentChar
  
  int currentChar()
  
  returns the current character without changing the IO pointer or index.
- hasChar
  
  boolean hasChar()
  
  Checks to see if there is a next character.
- consumeIfMatch
  
  boolean consumeIfMatch(char[] match)
  
  Useful for finding constants in a string like true, false, etc.
- location
  
  int location()
  
  This is mostly for debugging and testing.
- safeNextChar
  
  int safeNextChar()
  
  Combines the operations of nextChar and hasChar. Characters is -1 if not found which signifies end of file. This might be preferable to avoid two method calls.
- findNextChar
  
  char[] findNextChar(int ch, int esc)
  
  Used to find strings and their ilk Finds the next non-escaped char
  
  Parameters:
  
  ch - character to find
  
  esc - escape character to avoid next char if escaped
  
  Returns:
  
  list of chars until this is found.
- hadEscape
  
  boolean hadEscape()
- readNumber
  
  char[] readNumber()
  
  Reads a number from the character source.
- errorDetails
  
  java.lang.String errorDetails(java.lang.String message)
