Class DeflaterOutputStream

+--java.util.zip.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.

buf
protected byte[] buf
This buffer is used temporarily to retrieve the bytes from the
deflater and write them to the underlying output stream.
def
protected Deflater def
The deflater which is used to deflate the stream.
DeflaterOutputStream
public DeflaterOutputStream(java.io.OutputStream out)
Creates a new DeflaterOutputStream with a default Deflater and
default buffer size.
Parameters:
DeflaterOutputStream
public DeflaterOutputStream(java.io.OutputStream out, java.util.zip.Deflater defl)
Creates a new DeflaterOutputStream with the given Deflater and
default buffer size.
Parameters:
DeflaterOutputStream
public DeflaterOutputStream(java.io.OutputStream out, java.util.zip.Deflater defl, int bufsize)
Creates a new DeflaterOutputStream with the given Deflater and
buffer size.
Parameters:
Throws:
close
public void close()
Calls finish () and closes the stream.
deflate
protected void deflate()
Deflates everything in the def's input buffers. This will call
def.deflate()
until all bytes from the input buffers
are processed.
finish
public void finish()
Finishes the stream by calling finish() on the deflater. This
was the only way to ensure that all bytes are flushed in Sun's
JDK.
flush
public void flush()
Flushes the stream by calling flush() on the deflater and then
on the underlying stream. This ensures that all bytes are
flushed. This function doesn't work in Sun's JDK, but only in
jazzlib.
write
public void write(byte[] buf, int off, int len)
Writes a len bytes from an array to the compressed stream.
Parameters:
write
public void write(int bval)
Writes a single byte to the compressed output stream.
Parameters:
