java.lang.Objectjava.io.OutputStream
java13.io.FilterOutputStream
net.sf.jazzlib.DeflaterOutputStream
public class DeflaterOutputStream
This is a special FilterOutputStream deflating the bytes that are written through it. It uses the Deflater for deflating. A special thing to be noted is that flush() doesn't flush everything in Sun's JDK, but it does so in jazzlib. This is because Sun's Deflater doesn't have a way to flush() everything, without finishing the stream.
Field Summary | |
---|---|
protected byte[] |
buf
This buffer is used temporarily to retrieve the bytes from the deflater and write them to the underlying output stream. |
protected Deflater |
def
The deflater which is used to deflate the stream. |

DeflaterOutputStream(java.io.OutputStream out)
Creates a new DeflaterOutputStream with a default Deflater and default buffer size. |

DeflaterOutputStream(java.io.OutputStream out,
Deflater defl)
Creates a new DeflaterOutputStream with the given Deflater and default buffer size. |

Method Summary | |
---|---|
void |
close()
Calls finish () and closes the stream. |
protected void |
deflate()
Deflates everything in the def's input buffers. |
void |
finish()
Finishes the stream by calling finish() on the deflater. |
void |
flush()
Flushes the stream by calling flush() on the deflater and then on the underlying stream. |
void |
write(byte[] buf,
int off,
int len)
Writes a len bytes from an array to the compressed stream. |
void |
write(int bval)
Writes a single byte to the compressed output stream. |
