  org.bouncycastle.cms.CMSCompressedDataStreamGenerator

public class CMSCompressedDataStreamGenerator
extends java.lang.Object

General class for generating a compressed CMS message stream.

A simple example of usage.

      CMSCompressedDataStreamGenerator gen = new CMSCompressedDataStreamGenerator();
      
      OutputStream cOut = gen.open(outputStream, new ZlibCompressor());
      
      cOut.write(data);
      
      cOut.close();
