java.util.zip.DeflaterOutputStream
   java.util.zip.GZIPOutputStream

GZIPOutputStream
public class GZIPOutputStream extends DeflaterOutputStream (Code)
This class implements a stream filter for writing compressed data in the GZIP file format.
version:
   1.29, 05/05/07
author:
   David Connelly


Field Summary
protected  CRC32crc
     CRC-32 of uncompressed data.

Constructor Summary
public  GZIPOutputStream(OutputStream out, int size)
     Creates a new output stream with the specified buffer size.
public  GZIPOutputStream(OutputStream out)
     Creates a new output stream with a default buffer size.

Method Summary
public  voidfinish()
     Finishes writing compressed data to the output stream without closing the underlying stream.
public synchronized  voidwrite(byte[] buf, int off, int len)
     Writes array of bytes to the compressed output stream.

Constructor Detail
GZIPOutputStream
public GZIPOutputStream(OutputStream out, int size) throws IOException(Code)
Creates a new output stream with the specified buffer size.
Parameters:
  out - the output stream
Parameters:
  size - the output buffer size
exception:
  IOException - If an I/O error has occurred.
exception:
  IllegalArgumentException - if size is <= 0



GZIPOutputStream
public GZIPOutputStream(OutputStream out) throws IOException(Code)
Creates a new output stream with a default buffer size.
Parameters:
  out - the output stream
exception:
  IOException - If an I/O error has occurred.




Method Detail
finish
public void finish() throws IOException(Code)
Finishes writing compressed data to the output stream without closing the underlying stream. Use this method when applying multiple filters in succession to the same output stream.
exception:
  IOException - if an I/O error has occurred



write
public synchronized void write(byte[] buf, int off, int len) throws IOException(Code)
Writes array of bytes to the compressed output stream. This method will block until all the bytes are written.
Parameters:
  buf - the data to be written
Parameters:
  off - the start offset of the data
Parameters:
  len - the length of the data
exception:
  IOException - If an I/O error has occurred.
