public class GZIPOutputStream
extends DeflaterOutputStream
This class implements a stream filter for writing compressed data in the GZIP file format.


Variable Index

 o crc
CRC-32 of uncompressed data.

Constructor Index

 o GZIPOutputStream(OutputStream)
Creates a new output stream with a default buffer size.
 o GZIPOutputStream(OutputStream, int)
Creates a new output stream with the specified buffer size.

Method Index

 o close()
Writes remaining compressed data to the output stream and closes the underlying stream.
 o finish()
Finishes writing compressed data to the output stream without closing the underlying stream.
 o write(byte[], int, int)
Writes array of bytes to the compressed output stream.

Variables

 o crc
Properties Inheritable 
    crc=CRC32 
CRC-32 of uncompressed data.

Constructors

 o GZIPOutputStream
    method GZIPOutputStream(out=OutputStream, -
                            size=int) public Signals IOException
Creates a new output stream with the specified buffer size.

Parameters:
out - the output stream
size - the output buffer size
Throws: IOException
If an I/O error has occurred.
 o GZIPOutputStream
    method GZIPOutputStream(out=OutputStream) public Signals IOException
Creates a new output stream with a default buffer size.

Parameters:
out - the output stream
Throws: IOException
If an I/O error has occurred.

Methods

 o write
    method write(buf=byte[], -
                 off=int, -
                 len=int)  public    protect Signals IOException
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
off - the start offset of the data
len - the length of the data
Throws: IOException
If an I/O error has occurred.
Overrides:
write in class DeflaterOutputStream
 o finish
    method finish()  public     Signals IOException
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.

Throws: IOException
if an I/O error has occurred
Overrides:
finish in class DeflaterOutputStream
 o close
    method close()  public     Signals IOException
Writes remaining compressed data to the output stream and closes the underlying stream.

Throws: IOException
if an I/O error has occurred
Overrides:
close in class DeflaterOutputStream
