public void mark(int readAheadLimit)
throws IOException
mark in class ReaderreadAheadLimit - Limit on the number of characters that may be
read while still preserving the mark. Because
the stream's input comes from a string, there
is no actual limit, so this argument must not
be negative, but is otherwise ignored.
IllegalArgumentException - If readAheadLimit is < 0
