CMSCompressedDataParser

public class CMSCompressedDataParser extends CMSContentInfoParser
Class for reading a CMS Compressed Data stream. 
CMSCompressedDataParser cp = new CMSCompressedDataParser(inputStream);

process(cp.getContent().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.
