public class PGPCompressedDataGenerator
extends java.lang.Object
class for producing compressed data packets.
void | close() - Close the compressed object.
|
OutputStream | open(OutputStream out) - Return an outputstream which will save the data being written to
the compressed object.
|
OutputStream | open(OutputStream out, byte[] buffer) - Return an outputstream which will compress the data as it is written
to it.

close
public void close()
throws IOException
Close the compressed object.
open
public OutputStream open(OutputStream out)
throws IOException
Return an outputstream which will save the data being written to
the compressed object.
open
public OutputStream open(OutputStream out,
byte[] buffer)
throws IOException,
PGPException
Return an outputstream which will compress the data as it is written
to it. The stream will be written out in chunks according to the size of the
passed in buffer.
Note: if the buffer is not a power of 2 in length only the largest power of 2
bytes worth of the buffer will be used.
Note: using this may break compatability with RFC 1991 compliant tools. Only recent OpenPGP
implementations are capable of accepting these streams.
out
- buffer
- the buffer to use.
