    public int read(CharBuffer cb) throws IOException
    Attempts to read characters into the specified character buffer. The buffer is used as a repository of characters as-is: the only changes made are the results of a put operation. No flipping or rewinding of the buffer is performed.
    Parameters:
    @param cb the buffer to read characters into
    Return:
    @return @return The number of char values added to the buffer, or -1 if this source of characters is at its end
    Exceptions:
    @throws IOException if an I/O error occurs
    @throws NullPointerException if cb is null
    @throws ReadOnlyBufferException if cb is a read only buffer
