public class GZIPOutputStream
This filter stream is used to compress a stream into a "GZIP" stream. The "GZIP" format is described in RFC 1952.
| Field Summary | |

| Constructor Summary | |
|---|---|
GZIPOutputStream(OutputStream out)
Creates a GZIPOutputStream with the default buffer size |
|
GZIPOutputStream(OutputStream out,

void |
close()
Writes remaining compressed output data to the output stream and closes it. |
