Modifier and Type	Method and Description
static boolean	isEOL(int i) evaluate to true if i is a valid line terminator.
static boolean	isWhitespace(int i) evaluate to true if i is a valid whitespace.
AFM	parse(de.intarsys.tools.randomaccess.IRandomAccess random) Parse a AFM object from the input stream is.
byte[]	readLine(de.intarsys.tools.randomaccess.IRandomAccess input) read a single line.
void	readSpaces(de.intarsys.tools.randomaccess.IRandomAccess input) read all characters until EOF or non space char appears. the first non space char is pushed back so the next char read is the first non space char.
byte[]	readToken(de.intarsys.tools.randomaccess.IRandomAccess input) read a single token.
