final void com.quadcap.io.IO.copyStream (  InputStream  is,
OutputStream  os,
int  bps,
int  buffered
)  throws IOException [static]
 

Rate limited stream copy.

Copy the input stream to the output until EOF. An initial series of "buffered" bytes is sent with no rate limit, thereafter, bytes are streamed (in 4Kbyte buffers) at the rate limit "bps" bytes per/sec. No particular effort is made to buffer the incoming stream.
