available

public int available()
              throws IOException

Method is overridden to report number of bytes that can now be read from decoded data buffer, without reading bytes from the underlying stream. Never throws an exception; returns number of bytes available without further reads from underlying source; -1 if stream has been closed, or 0 if an actual read (and possible blocking) is needed to find out.
