java.lang.Object

org.bouncycastle.cms.CMSContentInfoParser

org.bouncycastle.cms.CMSCompressedDataParser

Direct Known Subclasses:

SMIMECompressedParser

public class CMSCompressedDataParser
extends CMSContentInfoParser

Class for reading a CMS Compressed Data stream.

     CMSCompressedDataParser cp = new CMSCompressedDataParser(inputStream);
      
     process(cp.getContent(new ZlibExpanderProvider()).getContentStream());
 

Note: this class does not introduce buffering - if you are processing large files you should create the parser with:

      CMSCompressedDataParser     ep = new CMSCompressedDataParser(new BufferedInputStream(inputStream, bufSize));
  

where bufSize is a suitably large buffer size.
