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 out any remaining data and closes the output stream.
o write(byte[], int, int)
Writes array of bytes to the compressed output stream.
o write(int)
Writes a byte to the compressed output stream.

Variables

o crc 
  protected CRC32 crc
CRC-32 of uncompressed data.

Constructors

o GZIPOutputStream 
  public GZIPOutputStream(OutputStream out,
                          int size) throws 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 
  public GZIPOutputStream(OutputStream out) throws 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 
  public synchronized void write(int b) throws IOException
Writes a byte to the compressed output stream. This method will block until the byte has been written.

Parameters:
b - the byte to be written
Throws: IOException
If an I/O error has occurred.
Overrides:
write in class DeflaterOutputStream
o write 
  public synchronized void write(byte buf[],
                                 int off,
                                 int len) throws 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 close 
  public synchronized void close() throws IOException
Writes out any remaining data and closes the output stream.

Overrides:
close in class DeflaterOutputStream
