public class CMSCompressedDataStreamGenerator extends 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();
