Class GZIPOutputStream
- Closeable, Flushable
This filter stream is used to compress a stream into a "GZIP" stream.
The "GZIP" format is described in RFC 1952.
protected CRC32 | crc- CRC-32 value for uncompressed data
|
void | close()- Writes remaining compressed output data to the output stream
and closes it.
|
void | finish()- Finishes the stream by calling finish() on the deflater.
|
void | write(byte[] buf, int off, int len)- Writes a len bytes from an array to the compressed stream.

GZIPOutputStream
public GZIPOutputStream(OutputStream out,
int size)
throws IOException Creates a GZIPOutputStream with the specified buffer size
out - The stream to read compressed data fromsize - Size of the buffer to use
finish
public void finish()
throws IOException Finishes the stream by calling finish() on the deflater. This
was the only way to ensure that all bytes are flushed in Sun's
JDK.
- finish in interface DeflaterOutputStream
write
public void write(byte[] buf,
int off,
int len)
throws IOException Writes a len bytes from an array to the compressed stream.
- write in interface DeflaterOutputStream
buf - the byte array.off - the offset into the byte array where to start.len - the number of bytes to write.
