Class 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();
