public void mark(int readAheadLimit) throws IOException
readAheadLimit

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
