public class GZIPOutputStream

extends DeflaterOutputStream

crc

CRC-32 of uncompressed data.

GZIPOutputStream(OutputStream)

Creates a new output stream with a default buffer size.

GZIPOutputStream(OutputStream, int)

Creates a new output stream with the specified buffer size.

close()

Writes remaining compressed data to the output stream and closes the underlying stream.

finish()

Finishes writing compressed data to the output stream without closing the underlying stream.

write(byte[], int, int)

Writes array of bytes to the compressed output stream.

 protected CRC32 crc

CRC-32 of uncompressed data.

 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.

 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.

 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

 public void finish() throws 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

 public void close() throws 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
